In order to make sure the safe mining of No. 13 mining area in Yanzishan Mine, the 13190 initial mining working face was taken as background, deep impact hazard was evaluated, F16 fault was the key factor leading rock blast hazard, based on geological conditions and anti-shock requirements of the working face, bolt-mesh-anchor + 5.4 m U steel support, ellipse canopy + bolt-mesh-cable support, 工 shape trapezoidal roof support were adopted in different area of 13190 working face, large diameter borehole pressure, coal seam water injection, coal deep hole explosion were applied to reduce the possibility of mining and rock burst in recovery mining.
