Panchengling Mine of Jinneng Coal Holding Group is a mine with coal and gas prominence. The original anti-surge measure of "pre-pumping coal seam gas in the strip of roadway through the layer drilling" with problems such as poor treatment effect, high construction danger, limited treatment space and time, seriously affected the gas treatment effect and mining succession. In response to this problem, combined with the actual conditions of the mine, the adjacent working face with low extraction roadway to pre-pump the gas in the strip area of the previous working face down-slot was proposed, which can provide technical support and safety guarantee for the safe and efficient production of the mine.
