Influence of coal seam thickness on pressure relief and energy releasemechanism of large-diameter drilling hole
The variation of coal seam thickness is one of the important factors affecting the pressure relief of large-diameter drilling hole. We have established an elastic model of pressure relief of large-diameter drilling hole based on the principle of equivalent elastic modulus. Taking two working faces o...
