Effective fracture zone under deep-hole cumulative blasting in coal seam
Deep-hole directional cumulative-blasting cracking technology has unique advantages for improving coal seam permeability. This paper was concerned with the range of the effective fracture zone under cumulative blasting using a linear-shaped charge in a coal seam. Based on the analysis of the mechani...
