Abstract: The rock cross-cut coal uncovering in gently inclined or thick coal seam has the characteristics of long distance and large amount of engineering, which is the key and difficult point of gas control. In order to improve the excavation speed of rock cross-cut coal uncovering in gas unusual area, the gas control technology is studied during the period of excavation, and the safeguard measures are proposed. By adjusting the supporting scheme in a timely manner, optimizing blasting management and reasonable organization construction, the time of coal uncovering is shortened by about 1/3, which can realize the rapid coal uncovering and effectively alleviate the pressure of excavation replacement of coal mine.
