摘要
从理论和实践两个方面阐述了水力割缝技术处理煤层瓦斯的作用机理，国内外试验应用这一技术，提高煤层瓦斯抽放率和防止突出的作用效果显著，并从各个方面对水力割缝技术的效果进行了较深入分析。
Mechanism of treating coal seam methane with hy-draulic cutting seam technique was described from two aspectsof theory and practice. This techinque have been utilized toachieve such remarkable effect as increasing ratio of draining- out methane and preventing projection at home and abroad.Deep analysis was made on the effect of hydraulic cutting seamtechnique of six aspects.
