| 摘 要： | 针对煤矿矸石地表堆积对人类生存环境和条件带来的威胁与危害，研究了矸石井下处理技术．该项技术运用开采沉陷理论预计地表允许沉陷范围内充填区域矸石充填压实后残余空间的最大高度，确定矸石充填巷的布置；基于数值模拟方法分析了充填巷两侧煤柱应力分布、消除充填巷开掘时的“多洞效应”问题，优化矸石充填巷掘进顺序；设计了矸石充填工艺．此项技术在邢东矿井得到成功应用，实现了矸石井下处理与建筑物下煤炭资源的开采利用．

| Abstract: | In order to solve the problem of heaping waste in aboveground,a technique of disposal waste in underground was proposed.Applying theory of mining subsidence and by means of the maximum height of residual space of the compacted filling-waste within the limits of mining subsidence,the layout of waste filling roadway was determined.Based on numerical simulation method to analyze stress distribution of coal-pillar of both sides of filling roadway and to remove 'mutual influence of multi hole' caused by driving filling roadway,the driving sequence was optimized and determined.The filling process of waste was designed.The technique has been successfully used in Xingdong Coal Mine and the good results of disposing waste in underground and mining coal resource under the surface building have been realized. |
