Wujia Mine, as a coal and gas outburst mine, in order to avoid coal and gas outburst accidents during working face mining, theoretical analysis, parameter design calculation and other means were used to study the mechanism and design parameters of advanced discharge drilling. The results showed that when there was a serious danger in the working face, it was effective to use the small-diameter dense discharge holes in the mining working face for gas emission.
