陈耳金矿深部开采巷道支护技术优化及应用

Research and application of deep mining roadway support technology in Chener Gold Mine

陈耳金矿已进入深部矿体开采阶段,井下岩爆现象时有发生,严重威胁到井下安全生产。为选择合适的井下巷道支护方式,采用Flac3D软件模拟喷锚网联合支护对深埋巷道地应力分布的影响,然后针对喷锚网设计参数进行合理的优化。通过井下现场应用,采用喷锚网联合支护技术大大提高了岩爆区域巷道顶板及两帮的稳定性及可靠性。

Chener Gold Mine has entered deep mining,and the underground rock burst occurs frequently,which seriously threatens the safe operation in underground mines.To choose the right means of underground roadway support,in this paper,Flac 3D software is used to simulate the effect of shotcrete-bolt-mesh support on the ground stress distribution of the deep buried roadways.Then the parameters of the shotcrete-bolt-mesh support process are reasonably optimized.Field application in underground mines show that the shotcrete-bolt-mesh combined support technology greatly improves the stability and reliability of the roadway roof and sides in rock burst areas.
