三道庄露天矿早期经过多年的地下开采,存在大量的地下空区。针对D区采空区规模大、形态复杂等特点,建立了36通道全数字型矿山微震监测系统,根据D区现场实际,确定了系统组成和监测范围,建立了三维可视化地质模型,对空区进行全天候、数字化实时监测,通过不同的事件波形分析监测区域的地压活动和岩体破裂事件,实现了对微震源的定位,为采空区的监测预警提供了有力的技术支持和重要的科学依据,对整个矿山的安全生产工作具有重要实际指导作用。
Sandaozhuang open-pit mine after many years of underground mining, there are a large number of underground areas. Aimed at the characteristics of large area and complicated shape of goaf in D area, a 36-channel all-digital mine microseismic monitoring system was established. According to the actual field in area D, the system composition and monitoring range were established. A three-dimensional visual geological model was established. All-weather, digital real-time monitoring, through the analysis of different event waveforms in the monitoring area of the ground pressure activities and rock mass rupture events, to achieve the location of microseismic sources, provide strong technical support for monitoring and early warning of goaf and important science Based on the entire mine safety work has an important practical guidance.
