Abstract
Outburst mine most easily lead to coal and gas outburst accidents in the process of rock cross-cut coal uncovering.The main measure to prevent and control coal and gas outburst in the work of rock cross-cut coal uncovering is pre-drainage coal seam gas by crossing hole.However,singly taking this measure is difficulty to achieve the ideal drainage elimination effect in low permeability coal seam.The drilling and enlarging intergration hydraulic reaming technology can effectively increase coal seam permeability and the efficient influence radium of extraction borehole.Combined with strict sealing,the high negative pressure drainage measures,the standard of rapid drainage is achieved,which ensures the safety of uncovering coal.关键词
