The theoretical analysis and the numerical simulation are used to study the roof movement of the upward mining and the mining pressure variation in inclined seams. In order to determine the mining sequence of Dananshan mine, the Dananshan mine coal seam group is analyzed according to geological conditions. Numerical analysis shows that the spacing between seams is adequate for the upward mining, which can be applied to seams 3, 4, 5 and 6, and then to seam 2., authors=LIANG Bing¹, SHAN Longhui¹, LI Gang¹, JIN Jiaxu², authorsList=LIANG Bing;SHAN Longhui;LI Gang;JIN Jiaxu, authorCompany=1.

articleAbstract=针对大安山煤矿煤层群上行开采回采巷道围岩控制、开采滞后、水平接替困难及单一工作面回采率不高等实际问题,分别运用理论推导和数值模拟分析方法对倾斜近距离煤层群上行开采的顶板运移及矿山压力变化规律进行了研究演算.为确定大安山矿煤层群开采顺序,根据大安山具体地质条件并结合现场实践对大安山煤矿各煤层进行分析,运用数值模拟分析的方法进行模拟研究.分析结果表明,煤层间的间距对能否采用上行开采具有决定性作用,模拟结果显示当依次开采3、4、5号煤层后,5号煤层顶板剪切破坏高度为18m,远小于6号与5号的间距35.98m.因此,大安山煤矿近距离煤层群采用上行式开采是可行的,结合现有开采技术条件,最终确定采用先对3、4、5、6号煤层进行上行开采,然后开采2号煤层的开采方案.,
