A Study of Positioning Approach of Underground Blasting Based on LS-DYNA Virtual Platform

Abstract

The illegal exploitation of coal mine in China has been a threat to the national economy and the security of people's lives. It is necessary to efficiently monitor the illegal mining of coal, guarantee the safety of exploiters and restrain these unlawful activities. In order to determine the location of the blasting center, the theories of earthquake positioning were applied to get the location of underground blasting in this paper. The feasibility of these theories was testified by simulating the explosions on LS-DYNA virtual platform, and the optimal distribution method of test systems was obtained by comparing the results of different placement methods. Experimental results show that Multi-point circumferential distributed placement is most suitable for determining blasting center.
