摘　　要：随着黄沙矿区开采向深部发展,地表和井下都出现了不同程度的地压和地质灾害。文章介绍了该矿区开采背景、地表和井下各种地质灾害情况,简要介绍了微震监测系统的特点;主要介绍了采用微震监测技术开展井下冒顶片帮监测和上部老采空区和地表露天坑边坡微震监测案例分析,分析了冒顶微震事件数和能率变化特点与冒顶片帮的关系,并成功地对冒顶片帮灾害进行预警;给出了上部老露天坑边坡微震定位位置、波形特征以及微震发生时间与雨季之间的相关关系。通过近一年的研究,证实了多通道微震监测技术在黄沙矿区地压和地质灾害监测预警中的实用性和有效性。With the development of deep mining in Huangsha mining area,there have been varying degrees of ground pressure and geological disasters both on the surface and underground.This article introduces the mining background,various geological hazards on the surface and underground of the mining area,and briefly introduces the characteristics of the microseismic monitoring system.This article mainly introduces the use of microseismic monitoring technology to carry out underground monitoring of roof falling and the case analysis of microseismic monitoring of upper old goaf and surface open-pit slopes.It analyzes the relationship between the number of microseismic events and energy rate changes of roof falling and slope,and successfully provides early warning for roof falling disasters.The microseismic positioning position,waveform characteristics,and the correlation between microseismic occurrence time and rainy season on the upper old open pit slope were provided.Through nearly a year of research,the practicality and effectiveness of multi-channel microseismic monitoring technology in monitoring and early warning of ground pressure and geological hazards in the Huangsha mining area have been confirmed.
