摘要
为解决三汇三矿松软低透气性高瓦斯煤层(K_1)抽采钻孔垮孔严重,瓦斯预抽困难,抽采达标时间长的问题,采取水力压裂冲孔技术对该矿-60m N_4石门揭穿K_1煤层时进行了处理,结果表明:在相同的地质条件下,和未采取措施的-60m N_6石门揭穿K_1煤层相比,减少石门揭煤抽采钻孔79个,抽采达标时间减少105天。
In order to solve the problem of borehole collapse hole and long time extraction in soft coal seam （ K1 ） with low permeability and high gas of The third coal mine of SANHUI,Processing technology of hydraulic fracturing, punching to solve in -60mN4 Shimen,which exposing K1 coal, the results showed that under the same geological condition, compared with -60mN6 Shimen , which also exposing K1 coal, without hydraulic fracturing punching, -60mN4 Shimen reduced to borehole 79 smoke coal, drainage standard time reduced by 954 days.
