金属矿山矿体围岩工程地质勘察在生产中的作用

摘要

Guangxi peak Mining Co., Ltd. is a non-ferrous metal mining and mining-based company, located in Nandan County, Guangxi Dachang Town, with mining mining depth, the peak increase in company with mining depth, deep inside the mine rock stress growing, the release of elastic potential energy rock and cracking damage is relatively common, damage to pressure activity, earthquake damage and disturbance produced more and more serious damage, to produce adverse effects on safety. Peak of the deep mine by a wide range of rock engineering geological survey, the overall structural rock underground mines, stability, and rock quality evaluation, summed up the peak＇s mine roof failure mode, the company made a deep mine rock peak stability hierarchical management methods and roof into indicators for different levels of roof made of different failure modes corresponding supporting means, control measures and monitoring methods. Operating area for the stope design and construction to provide a reliable basis for mine rock engineering geology%广西高峰矿业有限责任公司是一家有色金属采选为主的矿业企业，位于广西南丹县大厂镇，随着矿山采矿的深入，高峰公司随着开采深度的增加，深部矿岩体内部的应力越来越大，岩体弹性势能释放和开裂破坏比较普遍，地压活动破坏、地震扰动破坏和生产破坏越来越严重，给生产安全带来不利的影响。通过在高峰深部矿岩体进行广泛的工程地质调查，对井下矿岩体的整体结构性、稳定性和岩体质量进行了评价，总结了高峰公司井下顶板破坏形式，提出了高峰公司深部矿岩体顶板稳定性分级管理的方法和顶板划分指标，针对：不同级别不同破坏方式的顶板提出了相应的支护手段、控制措施和监测方法。为作业区域采场设计、施工提供可靠的矿岩体工程地质依据。
