Titlebook: Roof Water Disaster in Coal Mining in Ecologically Fragile Mining Areas; Formation Mechanism Yifan Zeng,Zhenzhong Pang,Xin Du Book 2023 Th

Anecdote

,Numerical Simulation Study on Mine Water–Sand Inrush Under Fluid–Solid Coupling,by the excavation activities, the roof rock is ruptured. Once the overlying aquifer is connected, the groundwater infiltrates the cracks, and the rock strength, shear strength, cohesion, and internal friction are affected by the hydraulic pressure of the groundwater.

混合物

Research on Deformation Damage and Permeability Evolution of Overlying Formations,The main coal-containing formation in the Yu Shenfu mining area is the Mid-Jurassic Yan’an Formation. The middle and upper parts of the section have good coal content and large thickness, and the lower coal seam is thin.

Interim

Myocarditis

,Physical Simulation Study of Mine Water–Sand Inrush Under the Fluid–Structure Interaction,The water–sand inrush accident is a dynamic process from gestation-development-end.

Heresy

Water Inrush Mode and Prevention Technology Under Bedrock Fissure Aquifers,Groundwater mainly occurs in rock voids, and the development of karst and fissures in rock mass is often heterogeneous and discontinuous, and their water conductivity and water storage capacity are also very different, which also makes the distribution of aquifer water abundance with great heterogeneity.
