【摘要】 基于微地震监测工程,研究了将监测结果在矿图上合成的方法,并以监测实例为基础,介绍了微地震定位结果在矿图上的合成和应用方法,做出了微地震事件在工作面推进方向上的投影和在沿倾向、走向剖面上的投影图.在此基础上,研究了采场覆岩空间结构、断层活化、超前支承压力分布规律、工作面导水裂隙带发育高度与微地震事件分布的关系.结果表明:合成图简洁直观地展示了监测结果,可以在采矿工程中广泛应用.更多还原

【Abstract】 Based on the micro-seismic monitoring results and in order to present the dynamical process of strata fracturing,the method of synthesizing the micro-seismic monitoring results into mining maps is researched and its application introduced.The projection maps of micro-seismic events along the directions of working face,strike and dip were obtained.On the basis of this,the relationship of the micro-seismic events with the spatial structure of overlying strata,the fault activation,the front abutment pressure,and the height of water flowing fractured zone was also probed.The results indicate that the synthesized map can visually and clearly show the micro-seismic monitoring results.Therefore,it can be widely applied in coal mining.更多还原
