哈图金矿地压监测系统的建立及应用研究

随着开采深度的增加,哈图金矿采场片帮、冒顶等地压灾害日益突出,因此建立了微震监测系统来监测地压灾害并进行预警。主要介绍了微震台网的优化设计,并通过标定爆破完成波速校正。波速校正结果表明:微震监测系统的定位误差为10m左右,能够满足矿山地压监测的需要。另外,基于微震事件信息分析了各中段的地压活动规律,并划分出潜在的地压灾害区域进行重点监测与分析。微震监测系统在哈图金矿得到了很好的应用,为矿山安全生产和管理提供了技术支撑。

The ground pressure disasters such as spalling and roof falling of the stope have become more and more prominent with the increase of mining depth in Hatu gold mine. Therefore the microseismic monitoring system is established to monitor ground pressure disasters and carry out early warning. This paper mainly introduces the optimization design of microseismic network, and completes the wave velocity correction through the marked blasting events. The wave velocity correction results show that the location error of microseismic monitoring system is about 10m, which can meet the needs of mine ground pressure. In addition, based on the microseismic events information, the law of ground pressure activity in each level is analyzed, and the potential ground pressure disaster areas are divided to focus on monitoring and analysis. The microseismic monitoring system has been well applied in Hatu gold mine. It provides technical support for mine safety production and management.
