特厚煤层综放工作面停采煤柱合理宽度确定
|
摘要
本文以特厚煤层综放开采的同煤塔山矿8105工作面为研究对象,通过煤体应力测试、巷道两帮松动范围测试、巷道围岩松动范围测试的方法,对特厚煤层综放工作面停采煤柱合理宽度的确定进行了研究,对塔山矿其他工作面停采煤柱宽度的确定具有指导意义。
This paper takes the 8105 working face that is used fully mechanized mining for the thick coal seam in Tashan Mine of Datong Coal Mine Group as the research object,through the methods of coal body stress test,the roadway's two-side loosening range test and the loosening range test of the roadway surrounding rock,the determination of the reasonable width of coal pillar that is stopped mining in fully mechanized working face of thick seam is studied,it has the guiding significance to determine the width of coal pillar that is stopped mining for the other working faces of Tashan Mine.
