Special Issue Information

Dear Colleagues,

The deep earth has garned significant attention due to its rich mineral resources and additional value. Minerals are mostly found in rock interlayers, resulting in many difficulties in resource extraction, such as rockburst, squeezing and rock collapse phenomena. To ensure the stability and safety of the resource extraction process, detailed analysis of intricate geology is required to fully understand different materials’ mechanical and structural properties. Finally, an effective systematic theory and method can be proposed for application in engineering practice. This Special Issue focuses on the latest advancements in mechanics and engineering technology for deep rock mass and soil. Topics of interest include, but are not limited to, the following:

  • Mechanical behaviors and characteristic evolution of deep rock and soil;
  • Deep resource exploitation technology and application;
  • Microstructural characterization;
  • Multifield coupled simulation;
  • Roadway surrounding rock stability control.

Pore space characterisation is important in assessing the strength and hydraulic characteristics of rock. This paper proposes a new relationship to estimate the porosity of natural rocks using the data from a scanning electron microscope (SEM) and a pore and crack analysis system (PCAS). The obtained results were compared with the data obtained from a series of conventional mercury intrusion porosimetry (MIP) experiments. Three different rocks, namely siltstone, sandstone, and coal, collected from a depth below 400 m, were investigated in this study. The results indicated that the proposed method of digital analysis could accurately identify the pore size and porosity values, which were in agreement with the experimental data. The relationship between the two-dimensional porosity estimated from the digital analysis and the three-dimensional porosity obtained from laboratory experiments was established. A few limitations on the use of the proposed method have also been identified and discussed. Full article
