Abstract

:
This study focused on the significance of underground mining in Pakistan, resulting in the employment of operational staff to undertake the primary tasks of this sector, such as explosions, rock excavation, mineral research, mining-supporting walls, and mine compactivity. Occupational accidents and illnesses arise due to the activities mentioned above because the working circumstances are not optimal. The decision-matrix risk-assessment (DMRA) approach, in which incidents are evaluated according to their severity and probability, was also utilized to improve working conditions, including public health and environment protection. To assess the risks and to select which actions should continue in the same manner, we highlighted hazards that need control measures and, as the last option, those that must be stopped. By taking into account the results of the study, corrective actions were proposed that can help avoid the occurrence of the presented accidents through applying occupational safety and health regulations issued by the Department of Minerals and Mines, which is a governmental entity responsible for both the issuing and the compliance to those regulations. The current study also outlined the requirements that must be reported under mining-related laws.

1. Introduction

Construction, agriculture, and mining are the most hazardous occupational sectors in the world [1,2]. Any industry should adhere to Health, Safety, and Environment (HSE) protocols concerning accidents and occupational diseases. Among the various occupational sectors, mining is considered an important source of income globally (China, USA, Russia, Australia, India, Saudi Arabia, Indonesia, and Brazil) [1,3,4,5]. Mineral/metal production is essential for modern life science because it is used in a variety of products such as cars, computers, houses, roads, electrical transmission lines, jewelry, and fertilizers, among others [6,7]. Mining investments foster economic development by directly and indirectly creating jobs, social development through campaigns, and overall community improvement, thereby contributing to poverty reduction [8,9]. Because of the growing market demand, the mining extraction business has expanded labor without following safety standards, increasing workplace accidents [10,11,12].
Although mining is now considered a cornerstone of the Pakistan economy, because of its unique geological conditions, Pakistan is blessed with enormous mineral deposits spanning an area of 600,000 km2 [13] (Figure 1). Pakistan has a diverse range of rock types, from Pre-Cambrian to recent, with remarkable geological and geomorphological characteristics [14,15]. Coal, copper, gold, chromite, mineral salt, and numerous more minerals are among the 92 known minerals, 52 of which are economically utilized [16,17]. Despite its vast resources, the mining industry is performing poorly. According to the recent Economic Survey of Pakistan 2019–2020, Pakistan’s mining and quarrying sector is declining by 8.82%, compared to a 3.19% decline last year, and the sector contributes only 2.51% to Pakistan’s Gross Domestic Product (GDP) growth. Mineral development has made a significant contribution to the economic and social development of several industrialized and emerging countries, including Russia, Australia, Canada, China, and Iran [18,19].
Mineral production safety is inextricably tied to a country’s economic-resources sector improvement and community development [20]. Numerous fatal incidents have been documented in Pakistan due to safety management’s insufficient enforcement of safety procedures (Figure 2). On 20 March 2011, 52 workers were killed after a mine collapsed in Baluchistan’s Sor-Range area (Figure 2a) [21]. On 9 February 2015, a similar catastrophe occurred in the coal mines of Khyber Pakhtunkhwa province, when 19 miners were killed in a mine collapse (Figure 2b). Similarly, on 13 August 2018, a total of 18 people were killed as a result of a mine collapse in Dukki, Baluchistan (Figure 2c) [22]. On 7 September 2020, at least 22 people died, and many are still fighting for their lives in hospitals after six units of the Pakistan’s legendary marble mines collapsed, resulting in large stones falls (Figure 2d). The most recent incident occurred in 12 March 2021, when six miners were killed in a blast at a coal mine in southwestern Pakistan, near the Afghan border (Figure 2e). The average incident rate of underground incidents at a national level is 11.7%.
The mining districts of Pakistan in four different provinces produce numerous commercial minerals, and these are the provinces with a large number of land transport routes. For the last ten years, underground mining has been one of the main economic activities of these provinces. In December 2019, Pakistan’s minerals production was reported to be 49,947,390 metric tons. It represents an increase above the previous December 2018 number of 49,104,146 metric tons. Table 1 shows the production records of four provinces (Baluchistan, Sindh, Khyber Pakhtunkhwa (KPK), and Punjab) from 2009 to 2019 based on data from Pakistan’s Federal Ministry of Sustainability and Tourism.
The continued growth of investment in these provinces’ mining industries results in increased production and thus the hiring of additional personnel and generates an abundance amount of dust. The dust may contain a variety of toxic metals. Dust and residues pollute the air with PHEs [23]. PHEs enter the body by dust ingestion, inhalation, skin absorption, contaminated food, and water. PHEs are toxic, durable, and bioaccumulable [24]. PHEs cause hypertension; irritability; stomach discomfort; nerve damage; skeletal issues; lung, liver, and kidney issues; intellectual deficits; fatal cardiac arrest; and cancer [25]. Underground mining is concerned with extracting minerals by excavating the land [26,27,28]. However, the working conditions to which workers are exposed during their shifts are suboptimal, and, as a result, work accidents and illnesses occur that affect workers’ quality of life [29,30].
The risk of accidents varies according to the nature of the mine, as labor perform their tasks in confined spaces, exposing them to hazardous conditions that can result in illness or death [31,32]. According to a 2004 report on Pakistan’s mineral industry by Work in Freedom, International Labor, Geneva, mechanical ventilators were installed in coal mines in Punjab beginning in 1970. Other mines, on the other hand, have continued to rely on natural ventilation methods. Despite their increasing depth, rock salt mines continue to rely on natural ventilation, although they use auxiliary and booster fans at some of the blind headings [33,34]. Electric safety lamps are required in mines that have been declared gassy. Non-gaseous mines, on the other hand, continue to use flame lamps for underground illumination. In Pakistan, the use of open-flame oil lamps in naturally ventilated underground mines is dangerous and detrimental to workers’ health [35,36]. Equipment for detecting the presence of poisonous gases is uncommon in gassy mines [37]. Rather than that, caged birds are introduced into mines, and their death or fainting indicates the presence of poisonous gas [38]. When miners pass out from inhaling poisonous gas, vinegar is forced down their throats to resuscitate them. Most private coal mines continue to operate using the traditional manual haulage system [39]. Mines in the public sector, which account for less than 5% of total mines, have mechanized coal’s underground and surface transportation to some extent. Even the most basic safety equipment, such as face masks or goggles, is rarely provided to workers [23,40]. The resulting statistics on workplace accidents in Pakistan’s mining sector are alarming [39]. On average, more than 100 people lose their lives annually due to illness.
The overwhelming majority of miners are illiterate, under-trained, and overworked. These factors, combined with pitifully low piece-rate wages that contribute to malnutrition and poor health and necessitate long work hours, contribute to an increased risk of workplace accidents (Figure 3) [41,42]. A list of the principal hazardous conditions in the mining industry of Pakistan includes poor ventilation, low illumination and smoke inhalation, strata control, lack of mechanization, gas explosion, spontaneous combustion, ineffective supervision, sub-letting of mining leases, legislation representing occupational safety and health in mines, and the use of personal protective and safety equipment’s (Figure 3) [38].
Although dispensaries were seen near mines in Choa Saiden Shah, Dandot Khushab, and Makerwal, doctors are a rarity, and there are no regular medical check-ups of the workers in any of the four provinces. According to KPK doctors’ statistics, an alarming number of miners are hospitalized regularly for occupational lung diseases (e.g., pneumoconiosis) [43]. Several miner respondents confirmed the prevalence of this disease. Additionally, several workers stated that they had spent a significant amount of money on treatment for this occupational disease. The additional “shock” of medical expenses invariably results in indebtedness for individuals with already low wages.
There are additional hazards that affect mining industry laborers. Ergonomic risks relate to the tasks performed by the worker and can result in damage to sensitive parts of the musculoskeletal system, such as injuries and improper postures [44]. Psychosocial risks include anxiety and stress disorders, which contribute to an insufficient work environment, such as workplace violence [45,46]. Machines cause mechanical injuries, resulting in particle projection and other injuries [47,48]. Electrical installations or equipment causes electrical hazards, resulting in electric shocks if not properly maintained [49].
The analytical estimation process (AEP, qualitative-based), proportional risk-assessment (PRAT, quantitative-based), decision-matrix risk-assessment (DMRA, quantitative-based), human error analysis techniques (HEAT), event tree analysis (ETA), and risk-based maintenance (RBM) are some of the techniques used to assess risk. The quantitative-based DMRA method was utilized to obtain the risk analysis. The primary goal was to: (1) identify risk based on accident data; (2) forecast danger in hazardous conditions to prevent future fatal accidents; (3) emphasize the company’s responsibility to optimize and manage risks; and (4) highlight the minerals and mining policies in Pakistan.

2. Methodology

The Pakistan Mineral Development Corporation is in charge of investigating complaints regarding mining incidents and safety. In this study, the risk was quantified using decision-matrix-assessment (DMA) techniques. It was accomplished through a questionnaire and an interview, as this is a systematic approach for estimating risk and characterizing it based on informed judgment. To cover the large territory, 28 mines are located in Punjab and KPK. The cities where mines are located are Khushab, Mansehra, Bheer-Haripur, Hasababdal, Abbottabad, Timergarah, Lower Dir, Sheringal, Dram Dala, and Lower and Upper Chitral (Figure 1).
The questionnaire and interview were performed in the first stage to cover the main information of underground mining to assess the risk, as shown in detail in Table 2. The risk value in the risk matrix is a particular value as an ultimate number of those values matching the categories of effects and probability. The probability was expressed as follows; if the prevalence is in the “Pr” scheme and the result of seriousness is in the “s” scheme, the hazard factor is then labelled as “h.” The probability was formalized as “minor,” “major,” “disastrous,” “impossible,” “anticipated,” and “often.”
The continuous growth of the underground mining business has necessitated the adoption and application of new technologies and the use of novel chemicals in the processing and extraction of minerals, hence increasing the hazards associated with the mining sector’s developing activities [7,50]. Increased activity increases employment, either directly or indirectly, and is proportional to increased risks, injuries, and even fatalities.
Excessive dust exposure is a major hazard factor for a variety of respiratory diseases. The upper respiratory tract can be irritated by short-term exposure to reparable dust. Over time, workers are at risk of developing tuberculosis, bronchitis, and occupational asthma due to long-term cumulative exposure [51]. The prevalence of occupational illnesses has increased due to a lack of progress in reducing exposure to chemical dangers in mines [52,53].
According to scholars such as Kirchsteiger [54] and Ni et al. [55], the categories on the hazard matrix’s sides should be arranged in order of increasing danger, from minor to significant, and increasing probability, from lowest to highest (Table 3).
Following the accident, the damages were rated based on the harm to the environment, human life, or the company’s financial standing, which means the accident’s severity. The prevalence of injuries may vary by many orders of magnitude. As a result, prevalence was measured on a logarithmic scale. A severe injury’s severity (outcome of seriousness) was also sometimes stated on a logarithmic scale to cover up the nature of the scale: for example, “unimportant” injury, “important” injury, “serious” injury, and “major” injury (Table 4).
Concerning the arranged categories on the risk matrix’s and the hazardous red data collected in the field, a risk matrix activity was developed according to the statistics above, considering the probability and the outcome of seriousness (risk matrix activity is marked by diagonal lines in Table 5 and Table 6).

3. Results and Discussion

Gul and Guneri [56] used decision-matrix risk assessment to rank the risks such that they were better suited to real-world situations rather than random numbers. A hazard-control hierarchy is needed to lower the hazards [57,58]. Control methods to mitigate hazards in the field may be determined using the order of hierarchy of control as in Zhou and Yang [59]. This sequence is the most effective technique for dealing with the hazard. If the optimal control method is not possible, the following steps may be used to reduce the hazard. Regardless of whether or not the decision-matrix risk-assessment (DMRA) method is used and based on the assessment of explosion-related activities, the mineral-bearing minerals are broken, and rock excavation products and equipment are destroyed [60]. In mineral exploration, the goal is to find out where the mineral deposits are located underground [61,62]. In mining, the goal is to test the wall for labor movement in the mine, and, in road accessibility, the goal is to transport the excavated minerals to the proper location within the matrix without causing any major harm or recoverable injuries [63,64]. Aside from a few serious casualties, many miners were wounded due to the industry’s preventative measures [65,66]. However, it is essential to remember that a member of the security crew was seriously injured during the rock excavation.
A hazard magnitude analysis was carried out using the MMG-15-Nov-2017 (Mineral and Mines Act, KPK, Pakistan), in which the actions are specified depending on the level of hazard associated with each work task. According to the data in Table 5 scheme 1, there have only been a few minor explosions, which implies no one has been harmed, and just one person has died due to them. The MMG-15-Nov-2017 (Mineral and Mines Act, KPK, Pakistan), on the other hand, is used to categories the intensity of the risk into four categories: high, medium, low, and minimal. As a result, in an explosion, the following actions should be taken: minimal hazard requires immediate attention; low hazard requires immediate attention and correction if necessary; and high hazard requires that immediate attention and security conditions are revised as soon as possible if they are not already. The risk is reduced to a bare minimum (Table 7). Onifade [67] and Gomes and Silva [24] suggested the following control actions for risks that are at the top of the explosion rankings (e.g., excessive exposure to heat, inhalation of blasting powder and smoke, and skin burns from a hot material are all serious risks in the mining industries).
Currently, the only control mechanisms for these kinds of hazards require workers to operate in safe conditions with appropriate tools and equipment [68,69]. The vacuum system in the mining room has to be strengthened as an additional control measure [70,71,72].
According to the data, about five incidents involving two severely wounded people have been linked to gravel mining, putting it exactly at the intersection of prevalence Pr-2: the severity of serious injuries related to a hazard factor H4 (Table 8). It has been established that they cannot provide any personal damage or significant injuries, even if one of them is to a woman’s fertility. A new death that happens unexpectedly and without warning should be prevented at all costs by adopting extra precautions. Hazardous mineral exploration and rock extraction should be subjected to several controls [7,73]. However, the MMG-15-Nov-2017 method is utilized for more precise outcome analysis. The following steps should be done based on the hazard of rock excavation products and equipment: low risk requires attention and, if necessary, correction; moderate and high risk requires immediate action. This activity has resulted in one fatality, and significant injuries with a high hazard factor need immediate medical attention (Table 8). According to Sanjana and Prathilothamai [74], Suryoputro et al. [75], and Ilo et al. [76], in the event of an emergency, a sprinkler and alarm system should be installed.
There have been 14 mineral-exploration incidents classified as minor or severe in severity. It has been proven that they can be given no personal damage but only one serious injury and no major injuries (Table 9). A further in-depth examination of the results (MMG-15-Nov-2017) shows that the risk of severe injuries is not that great (Table 9). Excessive noise is generated throughout the exploration and mineral-exploration processes [77,78]. To combat this, wear a pair of quality earplugs [79]. Employees who use earplugs regularly should monitor their usage [80]. Falling heavy equipment during replacement is the most significant danger [81]. As a consequence, stacking rules should be followed as a preventative measure.
The unimportant seriousness and important seriousness of 24 mining-supporting-wall accidents were classified. Moderate risks require attention and adjustments if necessary for mining-supporting-wall/internal supporting structures, while high-risk activities necessitate urgent attention and a review of security conditions (Table 10). When it comes to mine-supporting walls and compactivity testing, there is available protective equipment for the danger (such as equipment for assessing worker movement inside mine walls) [82,83]. Even so, if the protective gear is required to be permanently placed, a warning signal system must be put in place [84].
There were 61 accidents involving mine compactivity activities, with the severity ranging from minor to major (Table 11). It has been decided that no one will be harmed or killed, and there will be no injuries. According to the results of the MMG-15-Nov-2017 study, the following actions should be done to improve mine compactivity: pay attention to low risks, pay attention to high hazards, and make corrections where necessary (Table 11). Around 61 accidents occurred during road-accessibility activities that were categorized as minor or major. The road-accessibility activity shows a moderate degree of danger based on the MMG-15-Nov-2017, which shows that the risk of severe injuries is not great (Table 12).
The mine’s safety equipment should be examined on a regular basis to ensure that the oxygen level is kept under control [85,86]. Employees’ usage of earplugs should be monitored to ensure success. Additionally, there is a risk while using hand-drilling equipment [87]. Installing emergency stop wires throughout the mine’s line environment will be more effective in preventing hand finger jamming and wounding in the operating region. The following control measures should be implemented to minimize the hazards associated with explosions, rock excavation, mineral exploration, mining-supporting walls, and mine compactivity. While working, the operator must wear safety eyewear at all times. During mine labor, the miner must wear a hard protective safety helmet. The manufacturing hall’s operating area needs more coupling guards to avoid injuries and limb loss [88]. The risk assessment process should be seen as an ongoing one, and the effectiveness of control measures should be reviewed and revised as needed [69,89].

4. Law Policies of Mineral and Mines in Pakistan

A mining policy should be developed to avoid incidents and to improve labor standards in the country. Certain measurements have been presented for incident reduction safety in mining operations.
  • It should be noted that “uneducated” and “unskilled” are not comparable, and the idea that education determines skill level is incredible.
  • Off-nominal conduct may be a safety violation if the person doing it has not received proper training.
  • Due to the severe nature of mining hazards, it is hard to believe miners would purposefully endanger their own and their colleagues’ lives if properly educated and trained.
  • If miners lack the skills required to operate safely in a mine, inadequate training is the major cause. Mine owners, managers, and regulators are responsible for miner safety training.
Explosives in mining operations have resulted in several accidents, including fatalities, structural damage, mine slides, and uncontrolled subsurface reservoir blasting. The Pakistan government designed the Khyber-Pakhtunkhwa Act of 2013 to ensure appropriate explosive storage and management in mining. The appropriate department develops the controlled blast strategy. Although policies exist, they are not implemented, which leads to the incidence. Secondly, the Licensing Authority investigates mineral property damage caused by leaseholders. The leaseholders may be responsible for such damages if the Licensing Authority grants the holder a fair hearing. According to articles 47 and 47-A, the use of explosives in mining must be reported to the Department of Mines and Minerals. To produce any minerals, the mineral owner must use scientific techniques. Sub-article 6 of the Mineral Act 2017 states that holders of prospecting licenses must safely seal all holes and cover-up or fence any holes or excavations in the mining region. The ground surface and any structures harmed by mining must be repaired. Encroachment on a mineral lease territory is punished by up to five years of imprisonment and a fine of two million rupees. The leaseholder should submit monthly production reports and mineral dispatch to the Licensing Authority appropriately (Article 43-1). Monthly output returns must be accompanied by a challan showing royalty and other dues paid. Article 47-A sub-section-2 requires every leaseholder to install apparatus and equipment for mining scientific research.

5. Recommendations

The geological condition influences the panel arrangement, the mining process, and wall and roof management. Simple geological formations and excellent surrounding rock qualities are general geological traits. It is important to note that overburden characteristics, the mining depth (m), the angle of the mine, and the reservoir trend are essential parameters for mining-structure stability (damage of overburden strata, surface movement, and deformation). Subsurface-mining support systems provide mine stability, such as in Wongawilli strip and pillar mining. Strip mining reduces overloaded strata, surface movement, and deformation. Strip mining causes less surface subsidence than underground long wall mining. Some flaws include poor mining efficiency and excessive driving rater. Both the strip pillar and Wongawilli mining processes may benefit from technology. It tries to resolve issues with coal mining beneath buildings, railways, and water bodies. The US, Canada, Australia, India, and South Africa employ room and pillar mining. It is also used in Dongsheng, Da Liuzhuang, in Shanxi, Nantun, in Huangling, and in Yanzhou.
Mine stability is critical for effective operational management and safety criteria. Although specific ancient techniques are still used to evaluate mine strength and stability, technological advances have reduced costs and time. Mine Mobile Inspection Robots (GMRI) and Ground-Penetrating Radar (GPR) are the newest tools for predicting geological and structural stability in a growing nation. These technologies forecast the danger zone during mining operations, which is helpful for worker safety. The developing country’s government should adopt a mining strategy for standardized scientific mining to avoid future disasters.

6. Conclusions

The risk-assessment matrix allows organizations to categorize work incidents as orange (no injuries), yellow (recoverable injuries, one fatality, and many injuries), or red (multiple injuries, several deaths, and many injured). Risk assessors may use colors to alert them to workplace issues. In addition to the previous research, the following are methods to prevent workplace accidents and illnesses. Based on the resulting conclusion, we understand that, for explosions, ensuring workers are trained in the use and handling of explosives and providing protective gear are some of the most important preventative measures. Using and managing machinery and equipment poses physical, chemical, ergonomic, mechanical, electrical, and natural hazards. Emergency stops, machine and equipment operating training, an internal control license, and necessary PPE should be available. Work processes must contain hazard-based safety measures and constraints. personal protective equipment (PPE), repetitive postures and activities (RPA), hazardous chemical substances (HCS), and safe operation of machinery and equipment are among the topics covered in workplace safety training (M&E). Finally, staff should be educated on the importance of safe work practices. Safety training, secure work methods, material handling and storage, and manual load safety measures should be included in exploration and exploitation.
