中文摘要:

为实现在村庄建筑物不搬迁的情况下安全采煤、提高资源采出率、缓解矿井生产接替紧张的矛盾,结合矿区具体的地质采矿条件及地表村庄建筑物的现状,给出了条带开采设计方案.根据万年矿已有的地表移动观测资料,该矿区地表沉陷规律基本符合概率积分法.通过理论分析计算,确定了概率积分法的预计参数,并对地表移动和变形进行了预计,根据预计结果对村庄建筑物损害程度进行了分析和评价.研究结果表明,万年矿村庄下压煤采用条带法开采技术上可行,经济上合理.

英文摘要:

In order to realize coal mining in safety without moving villages, increase coal recovery ratio, and solve the conflict of mining and panel development, the strip pillar mining scheme under villages is presented. Combined with the specific geological and mining conditions and surface structures status in Wannian coal mine. Based on the existing observation results of surface movement and deformation in Wannian coal mine, the surface subsidence law of the coal mine basically accords with the probability -integral method. Through theoretical calculation and analysis, the prediction parameters of probability - integral method have been worked out, and the surface movement and deformations are predicted. With the predicted results, the damage extent of the buildings is analyzed. The results show that it is technically feasible and economically reasonable to use strip pillar mining under villages in Wannian coal mine.
