Effect of in-situ stress on the cracking and permeability enhancement in coal seams by deep-hole cumulative blasting
With the gradual development of coal mining to deeper levels, the in-situ stress of coal seams shows an increasing trend, resulting in a gradual decrease in permeability, and the stress state of the coal and rock mass and the properties of the surrounding rock also change. The mechanical properties...
