Research on Comprehensive Gas Control Technology for Coal Mine Comprehensive Mining Face
Through the analysis of the actual distribution of gas inside the 25703 fully mechanized mining face of a certain coal mine,based on numerical simulation and production experience,comprehensive gas control methods such as coal seam pre extraction,high extraction roadway extraction,high-level drilling,and goaf buried pipes are proposed,and the effectiveness of gas comprehensive control technology is verified in actual production.
