Study on Pressure Observation of Fully Mechanized Caving Faces in Coal Seams with Rock Burst Danger in Xiagou Coal Mine

Abstract:

Taking the first fully mechanized caving face in Xiagou coal mine as research background, through the pressure observation on the scene field of fully mechanized caving face with rock burst danger, this essay reveals the pressure appearance law of coal seams rock burst danger and concludes that the field roof structure of fully roof mining is more conducive to the release of coal rock stress compared to layered mining structure and this method plays a mitigation role on moving pressure shock of coal rock. The fully mechanized caving faces can be explored fast under safety conditions. The research results are of great theoretical and practical significance to the mining production with similar geological conditions.
