Research the Surrounding Rock Control and Law of Rock Pressure in Full-mechanized Mining Face in Thin Coal Seam
Because of the hard rock and hard coal condition of thin coal seam working face,a greater pressure on the working face during mining influence,can direct roof caving face the basic full of mined-out area,the main roof is local produced cracks,and the main roof pressure is not obvious.Therefore the authors take Shulan mining thin coal seam fully mechanized working face as the research background,using discrete component UDEC mined-out area on the face of the first weighting step distance,the periodic weighting step distance,rock fracture development research.The simulation results reflect the working surface rock movement regularity and the movement of surrounding rock pressure behavior through the analysis,which has important significance for the mine to achieve safe production.
