Based on the Qianjiaying 5 and 7 coal seam in 2871 mining working face, gas pumping method of 2876E heading face was optimized. Through a series of experiments on test site, then numerical simulation software was used for data analysis and comparison, in order to verify the optimization method of actual effect. Ultimately the mining working face with cross borehole replaced previous flat drilling, high density, multi angle drilling and fast pumping gas replaced the previous low density, single point of drilling and low pumping gas.
