摘要：In order to solve the technical problems of prevention and control of dynamic mining pressure in coal seam mining at the lower part of the room and pillar goaf with short distance coal seam, based on the surface movement deformation monitoring, the internal multipoint displacement monitoring of rock mass, the working face support resistance monitoring, the working face micro-seismic monitoring joint undermine and surface, integrated monitoring of stability of room and pillar goaf was realized, and the technical measures for preventing and controlling the dynamic pressure of longwall fully mechanized mining in the lower coal seam under the room and pillar goaf are proposed. The results show that integrative monitoring technology is a comprehensive, real-time and reliable method for monitoring the stability of room and pillar goaf, integrative monitoring technology has a good application effect on guiding the safe production of long wall fully mechanized mining under room and pillar goaf in western mining area and controlling the dynamic mining pressure.
