Title: Roof Stress Analysis and Roof Pressure Observation in Residual Coal Mining after Room and Pillar Mining
Abstract:For obtaining the roof deformation and destruction feature and stress distribution rule in residual coal mining after the room and pillar on the basis of longwall residual coal mining of 3#coal seam i...For obtaining the roof deformation and destruction feature and stress distribution rule in residual coal mining after the room and pillar on the basis of longwall residual coal mining of 3#coal seam in Xihe mine, Yangcheng of Shanxi coal transportation and sale group, the three-dimensional simulation experiment was established. In the mining process the experiment observed and recorded the stress and displacement of the immediate roof and main roof,it is reappeared the roof subsidence,breakage, collapse and the influence to the coal mining working face. Through the analysis and evolution of experiment data, researching the roof stress behavior in the residual coal mining was done.Read More
