微地震监测技术在地下工程中应用研究

微地震监测技术就是通过观测、分析生产活动中所产生的微小地震事件来监测生产活动的影响、效果及地下洞室围岩稳定状态的地球物理监测技术。与地震勘探相反，微地震监测中震源的位置、发震时刻和震源强度都是未知的，确定这些因素是微地震监测的首要任务。本文从定性、定量两方面系统介绍了微震事件定位、分类以及定位结果的分析，并结合工程实例验证方法的应用效果。

Application of Microearthquake Monitoring Technology in Subsurface Engineering

The microearthquake monitoring technology is the geophysical monitoring technology which is through observation and analysis of the small micro-seismic events happening in production activities,to monitor its impact,effects and stability of underground caverns' surrounding rock.In contrast with the seismic exploration,in the microearthquake,to monitor the position of seismic origin,the seismic origin time and the seismic intensity is unknown,and to determine these factors is the primary task.This paper introduces the location,classification of microearthquake event as well as analysis of the location result from the qualitative and quantitative aspects systematically.
