摘 要:针对河南省铁生沟煤矿具体的地质采矿条件及地表村庄建筑物的现状,通过理论计算分析,采用概率积分法进行地表移动和变形预计,对村庄建筑物下压煤条带开采技术进行了探讨,给出了条带开采设计方案及其开采参数.研究结果表明,铁生沟煤矿村庄下建筑物压煤采用条带法开采技术上可行,经济上合理,可以实现在村庄建筑物不搬迁的情况下安全采煤.该方法对提高资源采出率、缓解矿井接替紧张的矛盾具有实际意义.Based on the specific geological and mining conditions and surface structures status in Tieshenggou coal mine, Henan province, China, the strip pillar mining method under village structures was analyzed through theoretical calculation and prediction of surface movement and deformation. Then, the strip pillar mining plans and their parameters were presented. The results demonstrate that it is feasible in technique and reasonable in economy to extract the coal reserves under village structures by using strip pillar mining method in this coal mine, and coal mining in safety without moving village structures can be carried out. It is significant to increasing recovery ratio, solving the conflict of mining and panel development by using the method.
