Ascending Mining Feasibility Study

摘要

Coal seams ascending mining technology is very significant,since it influences the safety production and the liberation of dull coal,speeds up the construction of energy,improves the stability of stope and reduces or avoids deep hard rock mining disasters.Combined with the Xiaoming Ascending Mining Mine 4-1,by numerical calculation,the article analyzed ascending mining 4-1 factors,determined the feasibility of ascending mining 4-1 coalbed,proposed roadway layout program about working face,which has great economic and social benefits.
