摘　　要：针对碾子沟煤矿的不良地质条件和老空区分布现状,详细分析了既有矿井工业场地的地形特点、井筒位置、井下巷道层位等因素,提出矿井存在问题及优化开拓方案的思路,从技术安全和经济等方面对开拓方案进行全面比选,最终确定斜井开拓方案。根据现场实施情况证明,优化方案系统简单、土方工程量大大减小、井下巷道避开了铝土质泥岩的影响,工业场地内既有设施得到了有效利用。Aiming at the unfavorable geologic condition and goaf distribution of Nianzigou Coal Mine, the topographic features of industrial site, shaft location, and underground roadway position were analyzed, and the exiting problems and optimizing development plan were proposed, the inclined shaft development scheme was compared and determined according to the technical safety and economic efficiency. The field implementation showed that, the optimized system was simple, the earthwork volume was greatly reduced, the underground roadway avoided the influence of bauxitic mudstone, and the facilities in industrial fields were effectively used.
