摘要: 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。

Abstract: 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.

Key words: Underground mine, Extra-large mined-out area, Full-tailings filling
