Research on deep hole convergence energy blasting for increasing permeability in deep wells with high gas and low permeability coal seams

With the gradual deepening of coal mining, the issue of high ground stress will be faced. In response to the unclear understanding of the internal damage and fracture evolution of deep wells with high gas and low permeability coal seams under the influence of deep ground stress, a theoretical model...
