Special Issue Information

Dear Colleagues,

The deep areas and surface slopes of mines exhibit complex geological conditions. When combined with extreme precipitation and high-intensity mining activities, these conditions are highly susceptible to triggering a series of water-induced geological disasters, including landslides, water inrush, and rock pillar weakening. These events threaten the safety and stability of mining operations and lead to considerable resource wastage. Studying the occurrence mechanism, disaster prediction methods, and prevention measures of water-induced geological disasters can provide a theoretical basis and effective solutions for disaster prevention and resource utilization.

By studying the fundamental mechanics theory of water-bearing coal rocks, technologies for the resource utilization of mine water, mechanisms of surrounding rock water disasters, and advanced technologies for early warning and prevention of water-induced geological disasters, accurate prediction and rapid response to water-induced mine hazards can be achieved. This can minimize the losses caused by water-induced mine disasters and effectively utilize water resources in mines. Therefore, this Special Issue aims to discuss the latest advances in the theory and technology of water-induced mine hazard prevention and resource utilization.

All manuscripts related to the proposed topic are welcome. The Special Issue may include (without being limited to) the following themes:

  1. Fundamental mechanics of water-bearing coal and rock.
  2. Mechanism of surrounding rock water disaster.
  3. Theory and technology of monitoring, forewarning, prevention, and control of water-induced mine hazards.
  4. Mechanism and prevention techniques of landslides, debris flows, and erosion caused by rainfall on the surface of mines.
  5. Theory and technology of coordinated exploitation of coal–water dual resources.
  6. Resource utilization of mine water.
  7. Other related technologies for water-induced mine disaster prevention and resource utilization.

Given your competence in this area, we invite you to contribute a paper on the aforementioned subjects or any relevant issues.

Emergency water release from underground reservoirs is characterized by its suddenness and significant harm. The quantitative prediction of water spreading processes in mine tunnels is crucial for enhancing underground safety. The study focuses on an underground roadway in a coal mine, constructing a three-dimensional physical model of the complex tunnel network to explore the spatiotemporal characteristics of water flow spreading after water release in coal mine tunnels. The Volume of Fluid (VOF) model of the Eulerian multiphase flow was adopted to simulate the flow state of water in the roadway. The results indicate that after water release from the reservoir, water flows along the tunnel network towards locations with relatively lower altitude terrain. During the initial stage of water release, sloping tunnels act as barriers to water spreading. The water level height at each point in the tunnel network generally experiences three developmental stages: rapid rise, slow increase, and stable equilibrium. The water level height in the tunnel area near the water release outlet rises sharply within a time range of 550 s; tunnels farther from the water release outlet experience a rapid rise in water level height only after 13,200 s. The final stable equilibrium water level in the tunnel depends on the location of the water release outlet and the relative height of the terrain, with a water level height ranging from 0.3 to 3.3 m. The maximum safe evacuation time for personnel within a radius of 300 m from the drainage outlet is only 1 h. In contrast, areas farther away from the drainage location benefit from the water storage capacity of the complex tunnel network and have significantly extended evacuation opportunities. Full article

The fluctuation of reservoir water levels is a critical factor influencing the evolution of reservoir landslide–anti-slide pile systems. To investigate the reinforcement mechanism of anti-slide piles in reservoir landslides under the effect of reservoir water level fluctuations, this study employs numerical simulation methods to establish a three-dimensional slope model, simulating the drawdown process of the reservoir water level from 175 m to 145 m. The displacement and strain fields of the reservoir landslide during the water level drawdown are analyzed. Furthermore, the strain characteristics of the anti-slide pile-reinforced reservoir landslide under stress–seepage coupling are studied, and the prevention effectiveness of the landslide–anti-slide pile interaction system is explored. The results indicate that the drawdown of the reservoir water level can lead to the gradual expansion of the strain and displacement zones in the landslide, as well as a reduction in the safety factor. Under the effect of anti-slide piles, the maximum deformation of the reservoir landslide is significantly reduced. The optimal reinforcement effect is achieved when the anti-slide piles are arranged in the middle of the reservoir landslide, with a pile spacing of four times the pile diameter and an embedded depth reaching the critical depth. The findings of this study can provide a scientific basis for analyzing the instability mechanisms and mitigation of reservoir landslides. Full article

Performing stability studies of waterproof coal pillars is one of the key measures for preventing mine water disasters. As some areas of the coal pillar were affected by goaf water in the Nanhu Second Mine, the coal pillar and surrounding roadway were somewhat deformed. To investigate whether the pillar can ensure safe production in the mine, the source of goaf water and the direction of water infiltration were analyzed using exploration holes, and it was concluded that the goaf water originated from the V3 aquifer and was static. Thus, a theoretical analysis was carried out to determine the relationship between the mechanical parameters of the coal and rock structures affected by water. On this basis, a numerical simulation was employed to examine the key changes in the coal pillar and roadway affected by goaf water. The simulation results showed that the plastic area was 6–11 m and the elastic area in the middle was 6–8 m after excavating the working faces on both sides of the coal pillar, and the water flow vector of the aquifer could not pass through the pillar. Finally, in situ monitoring using ground-penetrating radar, deformation measurement, and loosening circle detection revealed that the development degree of internal cracks in the coal pillar was relatively light; thus, the pillar could effectively prevent water damage. These monitoring and analysis methods comprehensively evaluate the stability of the coal pillar and provide a guarantee for the safe mining of the working face. Full article
