| 摘 要： | 铜坑矿92#矿体的直接顶板就是开采91#矿体时的胶结或者非胶结的空区充填体,并且尚存在未充填采空区45万m3,使92#缓倾斜厚大矿体的上部形成大范围的隐患区,开采条件十分复杂,地压活动非常频繁。根据矿山实际建立了一套多通道岩体声发射监测系统(本文仅取其中的8个通道),对92#矿体的回采过程进行地压活动监测。本文在现场采集监测数据的基础上,对声发射事件数、波形等参数进行了分析,统计得出了铜坑矿92#矿体回采过程中采场应力场与声发射活动频度之间的相关关系。

| Abstract: | The direct roof of the 92# orebody in Tongkeng mine is the consolidated or non-consolidated goaf filling when mining the 91# orebody.Furthermore,over 450,000 m3 goaf are still unfilled forming a vast risk zone over the slowly inclined large and thick orebody,which leads to complex mining conditions and frequent geostatic activity.According to the actual situation of Tongkeng mine,a multi-channel AE monitoring system is established(this article only covers eight channels) in order to monitor the ground press... |
