In order to reduce the gas hazard in coal seams and effectively discharge gas at local locations, a new method of drilling cuttings volume and gas desorption index method was used for field measurement, and numerical simulation was used to study the effective discharge radius of bedding drilling at different discharge times and different apertures. Changes under the influence. The determination basis and method of the new drilling cuttings index method are expounded in detail, and the industrial test is carried out in Xiaoxi Coal Mine, Shanxi. For the discharge boreholes of the aperture, the effective discharge radius increases with the increase of the discharge time within a certain period of time; for the discharge boreholes of the same discharge time, the effective discharge radius increases with the increase of the aperture.
