摘要
黄山铜镍矿30#矿体采用无底柱分段崩落法开采,井下围岩节理裂隙发育,围岩破碎明显,局部已出现片帮及冒顶。本文根据矿山岩体岩性、节理裂隙发育及实际开采情况,对监测方案进行了设计及优化,并建立了地压监测系统。通过对微震监测数据的处理与分析,研究基于微震事件岩体应力及变形的变化规律,为矿山的安全生产提供了技术保障。
The 30#orebody of Huangshan copper-nickel mine was mined by pillar less sublevel caving.The surrounding rock had developed joint fissure,obvious broken.Spalling and roof falling had appeared locally.The monitoring scheme was designed and optimized,and the ground pressure monitoring system was established based on the conditions of rock lithology,joint fissure development and actual mining.Through the processing and analysis of microseismic monitoring data,the variation law of rock stress and deformation based on microseismic event was studied.It can provide technical support for mine safety production.
