Paper Title:
Research on Movement and Deformation Rules of Rock Strata between Coal Seams in Caving Method Upward Mining of Left-Over Coal with Numerical Simulation Method
  Abstract

In this paper, the process of upward mining in Baijiazhuang mine is analyzed by the simulation function in FLAC-3D software. Basing on the actual drilling column of the upward mining face in Baijiazhuang mine, the variation of rock pressure before and after upward mining is calculated and analyzed by means of numerical simulation model, and then the deformation and movement of the rock strata between coal seams before and after mining the upper and lower coal are further studied. Finally, the simulation results of studying the rock layer’s mechanical relationship and deformation condition is the same with actual mining.
