Study on Numerical Simulation Test of Mining Surface Subsidence Law under Ultrathick Loose Layer
In the process of coal mining, the surface subsidence under ultrathick loose layer is abnormal (subsidence coefficient greater than 1.0), which will cause great damage to the surface ecological environment. The fracture propagation and stress evolution of bedrock are of great significance to the pre...
