冬瓜山铜矿西山采空区治理工程研究与实践

冬瓜山铜矿西狮子山矿床是上世纪60年代始采的矿床，2002年闭坑后形成了一个特大空区群，这些采空区体积大、分布范围广，给矿山正常的生产带来了极大的安全隐患。为此，冬瓜山铜矿结合矿山自身的特点，经过多方面的调查、研究、论证，采用全尾砂对采空区进行了充填处理，实践中采用分步实施的原则,将东狮子山采空区作为试验地点，完善并取得成功经验后推广到西狮子山采空区应用。项目取得了良好的经济效益和社会效益。

Research of Treatment Engineering of Xishan Mined-out Area in Dongguashan Copper Mine and its Practice

The western Shizishan deposit of Dongguashan Copper Mine，is a deposit that has been explored since 1960s last century.A group of extra-large mined-out spaces are formed in 2002 with the feature of large volume and wide distribution.These mined-out areas bring great safety risks for normal production.For this，combining with its own characteristics，and based on the related investigation and research，Dongguashan copper mine treat the mined-out areas with full-tailing filling method.In practice，taking the eastern Shizishan mined-out area as a testing site，the mined-out areas are treated step by step.Then he successful experiences are fully applied in the Western Shizishan Mined-out area，with good economic and social benefits achieved.
