针对低透气性突出煤层瓦斯治理难题,试验研究了采用保护层开采和高压水射流钻割一体化为主的瓦斯抽采技术。本文介绍了回采工作面远程卸压保护预抽技术和高压水射流钻孔与切割试验情况和效果,煤层透气性系数显著增加,实现了瓦斯强化抽采,消除了煤层的突出危险性,在其他类似条件矿井具有推广应用价值。 Aiming at the problem of methane control in low permeability coal seam, the gas drainage technology using the integration of protective layer mining and high pressure water jet drilling and cutting is studied experimentally. In this paper, the conditions and effects of pre-pumping technology for pressure relief protection and high pressure water jet drilling and cutting at the working face are introduced. The gas permeability coefficient of coal seam increases significantly, and the gas drainage is enhanced to eliminate the prominent danger of coal seam. Similar conditions of mine has the promotion and application value.
