摘要

红透山铜矿是我国开采深度最大的金属矿山之一,地压问题突出。为分析深部采场稳定性和预防围岩破坏,在红透山铜矿-707中段47采场建立了中科微震高精度微震监测系统,经人工爆破检验,在采场多空区条件下系统定位精度满足矿山生产要求。实时监测结果表明:(1)采场围岩应力调整较快,大型爆破后未发生微震活动明显增加的情况,小爆破和出矿活动等现场作业与微震活动具有正相关性;(2)47采场开采过程中微震活跃区主要位于3502川、出矿口、-707主巷道和采场内部靠近通风井2等附近,现场踏勘发现,前3个区域在不同程度上存在明显的动力型破坏情况,与监测结果相符;(3)按区域进行围岩稳定性分析,有利于探究微震活动与大型爆破、小爆破和出矿活动等现场作业的关系,分析围岩破坏主导因素。

Abstract

Hongtoushan copper mine is one of the metal mine with largest mining depth in China,and the problem of ground pressure is prominent.In order to analyze the stability of deep stope and prevent the failure of surrounding rock,a high precision Zhongke microseismic monitoring system has been established in No.47 stope of -707 mining level in Hongtoushan copper mine.The positioning accuracy of the system can meet the requirements of mine production with multi-mined areas through artificial blasting test.The real-time monitoring results show that the stress of surrounding rock of No.47 stope is adjusted quickly,no obvious increase of microseismic activities after large blasting,and there is a positive correlation between field operations such as second blasting and ore extraction activities and microseismic activities.During the mining process,the microseismic active zone is mainly located near No.3502 tunnel,the ore outlet,-707 main roadway and the stope near the ventilation shaft 2.It is found that the first three areas exist significant dynamic failures by on-site reconnaissance,which matched the monitoring results.The stability analysis of surrounding rock based on regional division is helpful to explore the relationship between microseismic activities and large blasting,second blasting and ore extraction activities,and analyze the dominant factors of surrounding rock failure.
