Abstract: In order to solve the problem of excessive gas volume fraction in the upper corner caused by gas outburst in 18107
fully mechanized mining face of Wangjialing Mine of Jinneng Baode, a scheme of replacing roadway with hole by large-diameter
directional drilling was proposed. The actual monitoring results show that, this scheme effectively reduces the gas volume fraction,
and realizes long-distance, low-cost, high-safety gas drainage in a short-period project, and achieves the purpose of replacing
roadway with hole.

Key words: gas outburst; upper corner gas; large-diameter directional drilling; replacing roadway with hole
