水力冲割煤层卸压抽放瓦斯技术的试验研究表明了水力冲割煤层孔比普通钻孔抽放瓦斯量可提高７９％以上。为我国难抽煤层有效地抽放瓦斯开辟了一条新的技术途径。
Experimental study on gas drainage technology of hydraulic blanking coal seam shows that coal mines with hydraulic blanking can increase coal gas drainage volume by more than 79% compared with that of ordinary drilling. It has opened up a new technical approach for the drainage of gas in refractory coal seams effectively.
