Mining Safety and Sustainability, 2nd Volume

Topic Information

Dear Colleagues,

This Topic is a continuation of the previous successful Topic, "Mining Safety and Sustainability" (https://www.mdpi.com/topics/Mining_Safety). The mining industry has provided energy and raw material guarantees for global economic development and social progress. Especially in recent years, with the increasing improvement of infrastructure facilities and people's living standards, the demand for mineral resources/energy has gradually increased. However, with the increasing depth of mining, safety and sustainability are becoming ever bigger challenges for the mining industry. Detecting the mineral exploration environment, improving the safety of all processes of mining operations, developing intelligent mining equipment, and ensuring the optimization of the human–machine–environment in all mining processes have become necessary and important conditions for promoting mining works in terms of both safety and sustainability. This research topic aims to provide a platform for new research and recent advances in the safety and sustainability of mining. We welcome submissions by experts and scholars on the topics of safety mining, sustainable mining, mineral resource management, technology of intelligent mining, research and development of intelligent mining equipment, geomechanics and geophysics, green filling, mining methods, and sustainable mining.

Rock bursts pose a grievous risk to the health and lives of miners and to the industry. One factor that affects rock bursts is the dip angle of the coal seam. Because of the uniquely high gas content of the coal in a mine in Shanxi Province, China, coal specimens were obtained from this mine to produce coal–rock combination specimens and test the effects of various seam inclinations. Using a DYD-10 uniaxial compression system and a PCI-8 acoustic emission (AE) signal acquisition system, we investigated the spatial and temporal evolution characteristics of the burst tendency of specimens with different coal seam inclination angles (0°, 10°, 20°, 30°, 35°, 40°, and 45°). Uniaxial pressure was applied to the specimens, and we found that, as the inclination angle increased, the coal–rock combination specimens exhibited structural damage and destabilization, which was attributed to the generation of an interface slip phenomenon. In all tests, the coal exhibited greater damage than the rock. There was an energy convergence at the coal–rock interlayer interface, which was the main carrier for the accumulated energy. The impact energy dissipation index is defined according to the energy dissipation properties of the loading process of coal–rock composites. As the inclination angle increased, the impact energy dissipation index, energy storage limit, compressive strength, elastic modulus, and other indexes gradually decreased. This effect was strongest where the angles were 40° and 45°. The indexes used to assess the impact propensity decreased to a notable degree at these angles, revealing that the burst tendency of coal–rock is curtailed as the inclination angle increases. The results of this research are of great importance to the early evaluation of mine burst risks and the sustainable development of coal utilization. Full article
