Gas drainage technology of high fracture zone boreholes combined with coal seam boreholes is a popular and effective means of gas control. This paper takes the 10211 working face of the Shui Yu mine as the research object, on the basis of field test data, numerical simulation is used to scientifically select the negative pressure and reasonable spacing of boreholes in gas drainage, in order to improve the effect of borehole gas drainage in high fissure zone, improving the underground production environment, provide a reliable basis.
