摘　　要：针对大平煤业3号煤层透气性低的特点,采用水力割缝技术进行试验。通过连续观测瓦斯抽采浓度、抽采流量和抽采纯量等参数变化情况,对间隔割缝和全部割缝两种方式的实施效果进行对比分析。结果表明,间隔割缝效果优于全部割缝效果,可为矿井制定合理的水力割缝参数提供数据基础。In response to the low permeability of the No.3 coal seam in Daping Coal Industry,hydraulic cutting technology was used for testing.By continuously observing the changes in parameters such as gas extraction concentration,extraction flow rate,and extraction purity,and the implementation effects of interval cutting and full cutting methods are compared and studied.The results show that the interval cutting effect is better than the overall cutting effect,which can provide a data basis for the development of reasonable hydraulic cutting parameters in mines.
