Numerical Simulation of Coal Fracture Caused by High-pressure Air Blasting

More Information
  • Published Date: December 19, 2013
  • Based on porous medium permeability theory, air bursting caused coal fracture under different pressure is simulated with ANSYS software. The study results show that coal distribution range caused by blasting shock increases gradually with the increase of high-pressure air of blasting coal. The coal closed to the blasting hole is shocked larger, but the coal far away from the blusting hole is shocked less.
