冬瓜山铜矿深部矿体地压灾害治理方案研究

Study on control scheme of ground pressure disaster in deep orebody of Dongguashan copper mine

为了治理和控制冬瓜山盘区开采引起的井下地压危害,在充分调研冬瓜山矿段井巷工程及破坏状况的基础上,深入研究了冬瓜山矿段矿岩破坏机理,分析了各种支护方式破坏状况和产生破坏的原因。根据不同工程类型、工程位置、工程尺寸、工程岩性及破坏机理等因素,提出和制定了冬瓜山铜矿井下地压危害治理方案,以确保深部矿体的安全生产。

In order to control and control underground pressure hazards caused by mining in Dongguashan panel,on the basis of fully investigating the engineering and destroying condition of the tunnel in Dongguashan mining section,the failure mechanism of ore and rock in Dongguashan mining section has been deeply studied,the failure status and causes of various support modes are analyzed.According to different engineering types,engineering location,engineering size,engineering lithology and failure mechanism,etc,proposed and formulated the control scheme of underground pressure hazard in Dongguashan copper mine,to ensure safe production of deep ore bodies.
