Identification and Analysis of Multi-channel Microseismic Signals in Complex Production Environment in Huangsha Mining Area
This article introduces various seismic sources underground in the Huangsha mining area of Tieshanlong tungsten mine company.Based on extensive on-site monitoring,seismic phase analysis is used to identify the seismic signals generated by various underground signals such as blasting,mechanical operation equipment,personnel operation,rock mass fracture,etc.The basic characteristics of various seismic source waveforms are provided.At the same time,using fourier transform identification method in theory to further analyze the waveform of the interfered signal can better eliminate the interference of noise signals,extract useful signals,and correctly select the initial arrival time of the signal.The signal identification method introduced in this article is simple and easy to implement,and can basically meet the needs of extracting microseismic signals from rock mass fractures in daily monitoring of mines.
