Research progress on permeability improvement mechanisms and technologies of coalbed deep-hole cumulative blasting
Abstract Coalbed gas extraction is an important means of exploiting and utilizing gas resources, as well as a means of preventing coal mine disasters. In view of the low gas extraction rate from coalbeds with high gas content and low permeability, a method of improving permeability through deep-hole...
