Permeability enhancement of deep hole pre-splitting blasting in the low permeability coal seam of the Nanting coal mine
To solve the hidden danger of high methane and low permeability gas in the coal mining process, potentially affecting the safety production in an orderly way, we propose the use of deep hole blasting technology to improve the permeability of the coal seam gas drainage, increase the quantity and rate...
