| Abstract: | Through initial mining C0202 working face drilling extraction refinement innovation in Chiyu Mine, Shanxi Jindi Coke Mine Corporation Ltd., which realized “ drilling in place, good management, sealing hole, draining water”, improved the hole completion rate, orifice pressure reached more than 20 kPa, single extraction concentration more than 40%, part of the hole concentration more than 90%, the drainage volume was 2.3 times than the original, with obvious drilling effect, eliminated the gas accident and ensured the safety mining. |
