Establishment and application of microseismic monitoring system in Hongtoushan copper mine
Aimed at the situation of intensive ground pressure activities in Hongtoushan copper mine, microseismic monitoring system was established through optimized the layout of the sensors combined with the locate technique of microseismic monitoring and built three-dimensional geological model to make continuous and real-time monitoring on the ground pressure active regularity and an in-depth analysis was made on the data from the monitoring system. It suggested that the system can realize continuous and real- time monitoring through the research on the blasting record and the monitoring result. Locate precision test on monitoring system was carried out by man-made blasting. The analysis on comparison between monitoring result and actual coordinates of the blasting position suggested that the locate error of the monitoring system was less than 5 meters which indicated that the system had reached good precision for seismic source monitoring. The microseismic monitoring system could realize continuous and real-time monitoring on the ground pressure activities, capture the microseismic information caused by ground pressure activities and locate the seismic source which is significance for dynamic disaster prediction in deep mine.
