Technical scheme and application of pressure-relief gas extraction in multi-coal seam mining region
A pressure relief gas extraction technical model of a typical mining area is proposed based on coal and gas simultaneous extraction theory. Flac3D was employed to model vertical stress and displacement contour plot characteristics of non-outburst coal seam (No. 4) on top of outburst coal seam (No. 2...
