Study on the Technology of Enhancing Permeability by Millisecond Blasting in Sanyuan Coal Mine

To reduce gas disasters in low permeability and high-gas coal seams and improve gas predrainage efficiency, conventional deep-hole presplitting blasting permeability increasing technology was refined and perfected. The numerical calculation model of presplitting blasting was established by using ANS...
