Research on the Application of Microseismic Monitoring Technology for Geological Hazards Induced by Deep Mining in Huangsha Mining Area
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.
