摘要
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。
With the increase of mining depth, the ground pressure disasters such as spalling and roof falling have become more and more prominent in Hatu Gold Mine. Therefore, the microseismic monitoring system was established to monitor ground pressure disasters and provide early warning. The optimization design of the microseismie network was mainly introduced, and the wave velocity correction was completed by calibration blasting. The wave velocity correction results indicated that the positioning error of the mieroseismic monitoring system is about 10 m, which can meet the needs of mine ground pressure monitoring. In addition, the law of ground pressure activity in each middle section was analyzed based on the microseismic event information, and the potential ground pressure disaster areas were divided to carry out key monitoring and analysis. The mieroseismic monitoring system has been well applied in Hatu Gold Mine. It provides technical support for mine safety production and management.
