Abstract: No.15 coal seam of Baiyangling coal mine is gently inclined outburst coal seam.The workers of the coal mine have to face rock cross-cut coal uncovering frequently because of faults.There are faults in the expected sites of uncovering coal,and the sites are all in the place of mining stress stacked zones.In order to insure that the gently inclined outburst coal seam can be uncovered safely in the process of rock cross-cut coal uncovering in auxiliary shaft of shaft station,the governance modes of constructing exploration holes to control the site of coal seam,constructing advancing gas emission holes,checking the emission effect and safety uncovering coal have been put forward,and site practice has been carried out.Practice result shows that the effect of this method is remarkable,which can eliminate the dynamic phenomenon of uncovering coal to ensure the safety uncovering mine and improve mine construction speed.
