-440 roadway in soft rock roadway, surrounding rock is loose and broken, and is dominated by mudstone and sandy mudstone. To meet the demand of mine development, we expend -440 roadway. Based on the analysis of lithology of roadway, the paper puts forward the construction of combined support program, and takes industrial test and verifies the feasibility of supporting programs.
