摘　　要：为了研究煤矿开采诱发的断层滑移对村庄的影响,以我国东部某矿区内A村庄下采煤为研究对象,对开采前预计和实际开采后的损害结果进行了对比,分析了矿区内F26断层活化对A村庄建筑物的影响规律,并采用断层影响下的概率积分预计模型,定量计算出了断层滑移的影响,提出了避免断层滑移的村庄下采煤方案。结果表明:断层滑移形成的离层空间对开采沉陷的影响有促进作用,表现在建筑物损害等级和影响范围加大;断层影响下的概率积分模型在该矿区是符合的,A村庄下压煤的开采选用协调开采方案可较好地控制断层滑移。In order to study the fault sliding induced by the mining in the underground mine affected to the villages, based on a coal mining under a village within a coal mining area in East China as the study object, a comparison was conducted on the damage results before the predicted coal mining and after the actual coal mining and an influence law of No. F26 fault activation affected to the buildings in the vil- lage was analyzed. A prediction model of the probability integral under the influences of the fault was applied to quantitatively calculate the influences of the fault sliding and to provide the coal mining plan under the village to eliminate the fault sliding. The results showed that the bed separation space formed by the fault sliding wouht have a promotion role affected to the mining subsidence and could be showed in the building damage grade and influence scope. Under the influence of the fault, the probability integral model was fitted in the mining area and the coordinative mining plan selected for the coal mining under the A village could well control the fault sliding.
