Abstract
In view of the problems of “three lower” coal pressure in Dongping Coal Industry and the difficulty in moving villages and the exhaustion of mine resources, it is necessary to explore new mining techniques to realize the sustainable mining of existing coal resources. By means of theoretical analysis, laboratory test and field measurement, the paper puts forward the continuous green filling mining technology. The working face layout, filling material ratio, branch and lane parameters and surface deformation law were studied. This method has been used in the experimental mining of No. 15 coal seam of Dongping Coal Industry, and has obtained great economic and environmental benefits.
