摘要:

随着金青顶矿区开采深度的增加,地应力值逐渐增大,造成巷道围岩破坏越来越严重,且具有一定的岩爆倾向性。为进一步探究金青顶矿区深部开采诱发岩体破裂失稳规律,在金青顶矿区深部建立矿山微震监测系统,连续实时采集井下微震活动信息,对-825 m中段Ⅴ号矿体11#试验采场开采活动进行连续监测,重点分析开采扰动下岩体破裂前累计视体积、能量指数和施密特数等微震参数的变化特征, 得出当前矿体整体损伤程度较小,岩体破裂主要是由岩体开挖以及爆破振动引起。

关键词: 微震监测, 深部开采, 活动性, 岩体破裂, 金青顶金矿

Abstract:

It was found that the crustal stress increased gradually with mining depth,which resulted in the damage of surrounding rock more and more serious,together with a certain propensity to rock burst.In order to further explore the regularity of rock rupture instability caused by deep mining,microseismic monitoring system for continuous collecting microseismic activity information underground was established at Jinqingding mine area,continuous real-time information acquisition downhole microseismic activity.Ore body experiment on mining activities for continuous monitoring was carried out at 825 m-V orebody in the middle section of the 11#,with focusing on analysis of mining disturbance before rock burst under the cumulative volume,energy index and schmidt number change characteristics of seismic parameters,finally we concluded that damage degree of the current ore body was relative less,and rock mass fracture was primarily caused by rock mass excavation and blasting vibration.

Key words: micro-seismic monitoring, deep mining, activity, rock fracture, Jinqingding gold mine
