Abstract: Aiming at the problem of gas content overrun on upper corner and return airway in fully-mechanized face of high gas seam group in Shaqu Coal Mine, it analyzed the build-up and shift law of gas in the process of coal seam mining theoretically. Combined with the kilometer and directional drilling machine DDR-1200 which was imported from Germany, it proposed the gas extraction technology with the kilometer and directional drilling. According to actual mining conditions of 14205 working face, it established the parameters of the gas extraction, and carried out the industrial test. The results showed that, compared to the traditional high pumping roadway, the gas extraction technology of kilometer and directional drilling had obvious advantages, the concentration single-hole gas drainage reached 79%, and the maximum extraction scalar reached 12.8 m³/min, so that it achieved the safe and high-efficient exploitation of coal and gas.
