| Abstract: | Based on daily gas concentrations measured data in Baode coal mine 81304 fully mechanized caving face,combined with coal seam occurrence characteristics in working face,this paper found the root of gas overrun in the upper corner,and proposed directly comprehensive control measures of balancing pressure and gas drainage by buried pipe in gob,which completely solved the problem of gas gauge in the upper corner of working surface. |
