The distribution characteristics of blasting fractures and their engineering applications under the coupling effect of in-situ stress and energy-releasing end structure
As an effective technical means to improve the permeability of coal seam, pre-splitting blasting has important application value in the field of coal mine gas drainage. In order to accurately explore the distribution characteristics of blasting cracks under the coupling effect of in-situ stress and...
