| Abstract: | Supporting roadway for the 14#81005 coal face in Sitai coal mine of Datong, starting from the actual geological conditions, then analysis field theory. Study the factors affecting surrounding rock deformation situation about close coal seams, combined with numerical simulation FLAC, come to the supporting program more reasonable solutions and industrial experiments were verified, and achieved better results to determine distance seam roadway supporting program chosen to provide a strong support tool. |
