Microseismic Real-time Monitoring System Based on Virtual Instruments

Geological disasters such as rock burst coal and gas outburst in coal mines have inevitable link with micro-seismic phenomenon intrinsically. Monitoring the underground microseismic signals could determine the scope and extent of the underground rock and provide strong evidence for underground mine safety monitoring. A microseismic realtime monitoring system design based on virtual instrument was presented, using thirty two channels front microseismic signal processing unit, data acquisition card DAQ-6343, realizing multi-channel analog microseismic signals acquisition, achieved a real-time monitoring and analysis of microseismic signals combined with the microseismic method and improved adaptive wavelet transform processing algorithms in the LabVIEW platform. System monitoring results agree well with the actual mine earthquake, the error of obtained positioning results is small, realizing a real-time microseismic monitoring and analysis.
