摘　　要：为解决晋平煤业村庄下压煤开采难题,依据其采矿地质条件设计巷式充填开采工艺及施工方法,建立地表位移监测线研究地面移动规律。结果表明:支巷围岩变形微小,地表下沉量最大为27 mm,1501充填工作面开采对建筑物损害程度在Ⅰ级影响范围之内,最大限度地解放了村庄下压煤,并有效保护了地表建(构)筑物,取得良好的经济效益。To solve the problem of downward pressure coal mining in villages of Jinping Coal Industry,a roadway type filling and mining process and construction method are designed based on its mining geological conditions,and a surface displacement monitoring line is established to study the law of ground movement.The results show that the deformation of the branch roadway surrounding rock is small,and the maximum surface subsidence amount is 27 mm.The degree of damage to buildings caused by the 1501 filling working face mining is within the scope of Class I impact,which maximizes the liberation of downward pressure coal of the village and effectively protects surface buildings(structures),achieving good economic benefits.
