Abstract: In order to meet the extremely long drilling requirements at the 60102 working face of Hexi Coal Mine in Fenxi Mining, and based on the actual geological conditions in the underground coal mine, a technique for long-distance directional drilling in coal mines has been proposed.This technique utilizes the ZDY15000LD high-power directional drilling machine, to address the issue of insufficient drilling power in traditional drilling equipment.A telemetry system is employed to ensure stable signal transmission during the directional drilling process.A new high-pressure water supply system and specialized drill pipes are used to tackle the problem of pressure loss in the circulating drilling fluid.The resistance encountered during drilling was reduced through pressure-increasing and resistance-reducing drilling and multiple-progressed resistance reduction drilling, while the problem of low accuracy in drilling branch holes was addressed using a combined drilling side holes and branch control technology.Practical applications have shown that this technology significantly improves drilling efficiency and precision, with positional deviations measured at less than 0.11%,and a 100% success rate for achieving a first-time-fit in drilling operations, realizing a breakthrough in the field of directional drilling for long-distance gas extraction in coal mines.
