Abstract

Geological disasters caused by mining activities in the Wudong coal mine are mainly ground crevice and ground collapse. Therefore, making a thorough investigation of the type, size and distribution of geological disasters in the mining area and analyzing the causes, damage degree and development trend of the geological disasters are very important for the green mine construction and sustainable development. With the WorldView-2 data as the basis, on the basis of the establishment of remote sensing interpretation keys, by using the methods of the combination of remote sensing interpretation and field verification and the combination of human-computer interactive interpretation and computer automatic information extraction, the author delineated the geological disasters points and centralized growth areas caused by mining activities in the Wudong coal mine, and. measured the distribution direction, geometric parameters and influenced area of the geological disaster bodies. An analysis shows that the special shape and distribution features of ground crevices and ground collapses in the Wudong coal mine result from the joint action of the coal seam condition, coal mining exploitation technology and coal seam roof management mode, geotechnical engineering stability of the seam roof and floor slate. The results obtained by the author provide the data basis for prevention and control of geological disasters by Wudong coal mine's relevant management department.
