Study on the Stress Field and Crack Propagation of Coal Mass Induced by High-Pressure Air Blasting
High-pressure air blasting (HPAB) is one type of physical blasting technique that enhances the extraction rate of coalbed methane by impacting the coal mass with high-pressure gas to create cracks within it. First, based on the physical and mechanical parameters of the simulated coal rock mass, the...
