摘　　要：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。For the micro-seismic monitoring results and can present the dynamical process of strata fracturing, the method of synthesizing the micro-seismic monitoring results into mining maps was re-searched. The digitized mining maps, the micro-seismic monitoring results and accident data are re-spectively transformed into global, working face and fixed working face coordinate systems and are jointly processed. The processed results are visualized simultaneously by overlaying on each other in the time-spatial domains. All proposed techniques have been packed into a single software package for the optimized platform. This package enables us to visualize in real-time easily and efficiently and interpret monitoring results. The package has been deployed in several mining sites and highly evaluated. There-fore, it can be widely applied in coal mining.
