摘　　要：为有效回收矿井永久煤柱,缓解矿井资源紧张局面,以大宁煤矿地质条件为背景,采用现场试验方法,对厚煤层条带式矸石充填开采技术进行了研究与应用,确定了条带式支巷掘进与充填开采方案,设计了矸石充填工艺流程、矸石膏体充填材料配比以及掘进支巷支护方案。目前已完成两条支巷的掘进充填作业,根据地表下沉观测结果,各测点均未出现变形,因此该开采方案具有较好的可行性。In order to effectively recover the permanent coal pillars in the mine and alleviate the shortage of resources in the mine,based on the geological conditions of Daning Colliery,the author studies and applies strip-map coal waste back filling min-ing technology in thick coal seam by using on-site testing methods,then determines strip-map roadway driving and filling mining scheme,and finally designs the process flow of gangue filling,the ratio of gangue gypsum filling materials,and the excavation support roadway support plan,whose construction results prove that it is feasible.
