文摘

High-pressure air blasting experiment is conducted on concrete specimen to observe crack distribution. A damage model for high-pressure air blasting is proposed to simulate the damage patterns. Gas drainage enhanced by high-pressure air blasting is quantified based on the numerical simulations.
