The application of IMS microseismic monitoring technique in Piaotang tungsten mine

IMS microseismic monitoring technique was applied to ground pressure microseismic monitoring in Piaotang tungsten mine,and the monitoring system was established.Five single-channel detectors and a three-channel detector were installed at the stage of +496m、+388mand +268min the mine and 24hours' continuous monitoring of rock mass microseismic events had been realized.A large number of source parameters of microseismic events such as spatiotemporal data、errors、magnitude and energy et al were obtained and danger areas were successfully founded.It provides the basis for the work safety and mining scheme in mining area.
