深井高应力矿床开采地压监测与分析

Monitoring and Analysis of Ground Pressure for Mining a Deep High-stress Ore Deposit

针对冬瓜山深井矿床开采具有岩爆倾向的特征,提出了应力变形的监测系统方案,并根据实际监测结果进行了矿床开采围岩应力应变分析。实践表明,监测系统的建立及对监测数据的分析,更好地揭示了冬瓜山深井矿床开采围岩的地压活动规律,对矿山安全生产具有重要指导意义。

In the light of rockburst proneness during the mining of deep high - tress ore deposit in Dongguashan Copper Mine, a scheme was put forward for the construction of the stress and deformation monitoring system. The analysis of stress -strain of surrounding rock for the mining deposit was carried out according to the monitored results. The practice proved that the construction of the monitoring system and the analysis of the monitored results preferably discover the law of ground pressure activities in mining the deep deposit, which has an important guidance significance for safe production of the mine.
