Experimental Study on Damage Fracture Law of Coal from Solid-Propellant Blasting
The low permeability of coal seams has always been the main bottleneck restricting coalbed methane drainage. In this paper, a coal seam anti-reflection technology with solid-propellant blasting was proposed, and the composition and proportion of the solid propellants were determined based on the pri...
