Research of support technology on mining softrock roadway

This paper puts forward support mode, construction process and equipment selection of softrock roadway based on the theory analyze and field experiment. Lithologic determination, crustal stress analyze and nonelastic deformation calculation have be done to analyze the deformation behaviors of deeply softrock. Lastly the applicability and economic performance were proved through the analyses of the monitoring data. The S2S2 haulage roadway of Xiaokang coal mining is taking as case study.
