摘要
该文以大采高工作面合理停采线煤柱宽度为研究对象,以塔山煤矿8105工作面为研究背景,采用理论分析、数值模拟计算相结合的方法,对特厚煤层超前支承压力分布规律、停采线煤柱内部应力分布规律等进行了系统的研究。
In this paper the research object is based on the reasonable stop line width of coal pillar of the thick coal seam with the background of 8105 working face in Ta Shan Coal Mine. Study the distribution of abutment pressure, internal stress distribution of coal pillar and the deformation and fracture of the roadway surrounding rocks by combining the methods of theoretical analysis, field measurement and numerical simulation.
