为了使微地震监测结果能有效地反映岩体破裂的动态过程,研究了微地震定位数据在矿图上合成显示的方法。将数字化的矿图、微地震定位数据和事故数据分别转换到大地、工作面和固定工作面3个不同的坐标系中,实现了矿图、微地震定位数据和事故数据在不同时空域中的联合处理和显示,并开发了基于矿图的微地震事件时空域可视化处理软件。现场使用结果表明:在不同坐标系中,基于矿图的微地震事件时空域可视化图件,直观地展示了微地震定位数据与岩层破裂的动态过程和特点,可以在采矿工程中广泛应用。
In order to make the microseismic monitoring result reflect the dynamic process of rock mass rupture effectively, the method of synthesizing and displaying microseismic locating data on the mine map is studied. The digital mine map, microseismic location data and accident data are respectively converted into three different coordinate systems of the earth, the working face and the fixed working face, so that the mine map, the microseismic locating data and the accident data in different time-space domains Joint processing and display, and developed a time-domain visualization processing software of microseismic events based on the mine map. The results of field use show that in different coordinate systems, the time-space visualization maps of microseismic events based on mine-chart can directly display the dynamic process and characteristics of micro-seismic location data and fracture, which can be widely used in mining engineering.
