A study on high precision source location error control method based on microseismic monitoring cloud service platform

Abstract

With the increasing depth of open pit mining in our country, a large number of high and steep slope is produced, slope stability problem has become increasingly prominent, landslide accident has become a major hidden danger in surface mining safety production. As an effective slope monitoring and early warning method covering the whole mine, microseismic monitoring technology has been widely used. In this paper, the location accuracy of the source of microseismic monitoring on open-pit slope is quantitatively evaluated through the research of the slope location error control method. The effectiveness of the slope microseismic location error control method is verified through the fixed point blasting inside the network, which provides effective guidance for the microseismic data processing, so as to improve the location accuracy of slope microseismic. Rock fracture source location results are sent to the microseismic monitoring cloud service platform in real time. In order to improve the accuracy of rock mass stability analysis, so as to ensure mining safety.
