矿山深部开采试验采场地压监测技术研究

某矿深部开采过程中面临着较大的地压灾害问题,为确保下部矿体安全高效的回采,对试验采场采用垂直束状深孔爆破方式进行回采,并对回采过程中的岩体应力和变形情况进行监测分析。数据分析结果有助于进一步掌握开采过程中的地压活动规律,为深部矿体安全高效开采设计提供依据。

The research on monitoring ground pressure of deep mining in a testing stope

The possibility of disasters caused by ground pressure rises during deep mining of a mine in phase IV. To ensure the safety underground and the effectiveness of mining, it is determined to apply the vertical Bunch-Long-Holes Blasting as the method for mining in the testing stope. During the mining process, the rock stress and deformation are monitored. The final analysis of the data could assist to understand patterns of the activities caused by ground pressure and provide the references for the safety and high efficiency mining design of deep mining.
