Abstract: The analysis of the influence of deep metal filling mining on the surface is one of the key problems in the design of deep underground mining.Aiming at the reconstruction and expansion mines with existing underground mining projects, a reasonable underground microseismic monitoring system is designed to carry out medium and long term microseismic monitoring.The medium and long term spatial and temporal distribution of microseismic events induced by underground mining, microseismic stress and microseismic deformation characteristics were analyzed.Therefor, the influence of deep filling mining on the surface was evaluated.The results show that during the monitoring period, microseismic events are mainly concentrated near the mining level, and only a few small magnitude microseismic events occur near the surface.Underground stress concentration area and large deformation area are located near the mining level, and micro-fracture events induced by underground mining do not appear near the surface, indicating that underground mining has little influence on the surface.The research provides a new technical idea for evaluating the impact of deep underground mining on the surface and a useful reference for similar mining strata movement analysis.
