摘要
本文在分析瓦斯的危害及国内外水力压裂技术研究现状的基础上,通过平沟煤矿011605工作面进行水力压裂技术增透、强化瓦斯抽采的应用得出结论,水力压裂后煤层透气性系数最大可提高108倍,煤层从难抽放煤层变为可抽放煤层;水力压裂后压裂区域煤层瓦斯抽采浓度是非压裂区的2倍以上,瓦斯抽采的效果有明显的提高。
On the basis of analyzing the harm of gas and the research status of hydraulic fracturing technology at home and a- broad, through the trench coal mine 011605 face anti -reflection hydraulic fracturing technology, strengthening the application of gas extraction came to the conclusion that after hydraulic fracturing of coal seam permeability coefficient can improve the largest 108 times, severs drainage of coal seam coal into coal seam can be draining; After hydraulic fracturing fracture area of coal seam gas extraction concentration is fracturing zone, more than 2 times, the effect of gas extraction has obvious enhancement.
