Abstract:Coal resources are the most widely used basic energy resources in China. Exploraion beyond the approved limits in mining areas has strong concealment will not only disrupt the order of mineral resource development, but also easily form safety hazards and affect the safety production of coal mines. In this paper, taking Chenmanzhuang coal mine in Shanxian county as an example, the application of three-dimensional infrared laser scanning monitoring in the verification of super layer boundary in coal mines underground has been introduced. 3D infrared laser scanning is mainly used to collect point cloud data of underground mines, compare and analyze coal mine development and utilization plans with 3D point cloud data, and timely and effectively discover whether there are problems in underground mining. Comparing and analyzing the point cloud data of the entire underground mine with three-dimensional model of the mining range boundary, exploraion beyond the approved limits in mining areas can be determined. It will provide some refereces for protecting coal resource and determine the exploraion beyond the approved limits.
