Stress wave propagation and crushing mechanism of soft-hard composite coal under water-jet impact load
Abstract Composite coal seams have the characteristics of large differences in coal quality, difficulty in coalbed methane extraction, and poor permeability. In this work, the smooth particle hydrodynamics (SPH) method is employed to simulate the crushing process of composite coal impacted by water...
