摘　　要：低透气性高瓦斯薄煤层回采时,利用煤层高压注水压裂,增加煤层透气性,使煤体中的瓦斯得到充分释放;并配以充足的风量,解决采煤工作面上隅角及回风瓦斯超限问题,以保证采煤工作面的安全回采。The low-permeability and high gas thin coal seam is mined by high-pressure water fracturing coal seams to increase the coal permeability,it can make coal gas in the full release,with plenty of air volume,can solve the problem of gas gauge mining at corner work face and return air and to ensure coal face safety mining.
