Evidence in Earth Science Mechanisms of abrupt surface subsidence induced by repeated mining beneath residual coal pillars: a case study of Tashan Coal Mine, China

Mechanisms of abrupt surface subsidence induced by repeated mining beneath residual coal pillars: a case study of Tashan Coal Mine, China

Clarifying the formation mechanism of residual pillar instability and abrupt changes in surface subsidence induced by repeated mining beneath residual coal pillars is important for subsidence-hazard prevention and control under this special geological and mining condition. Based on the 8104 working face of Tashan Coal...

A Quasi-Continuous Visual Monitoring Method for Dynamic Deformation of Rock Strata in Similar Material Models

Similar material simulation is a primary experimental approach for studying strata movement and deformation. With increasing research depth, continuous monitoring of deformation in similar material models is urgently needed to obtain the corresponding relationships between underground mining and overburden and surfac...

Study on the Transmission Mechanism and Evolution Law of Surface Deformation in Abandoned Goafs Under Groundwater Action

The intrusion of groundwater inevitably alters the environment within the caving zones of mined-out areas and affects the mechanical properties of the surrounding rock mass, thereby influencing surface deformation. To investigate the deformation mechanisms of overburden and surface under the influence of groundwater in...
