Application of Reserved Withdrawal Roadway in Coal Mining Face

Through introducing experience and appliction effect of withdrawal roadway technology in actual production of coal mining face during ending period, the paper focuses on the construction method, precautions, technical requirements and support parameters, and provides support scheme of withdrawal roadway. Combined with the previous successful example of withdrawal roadway technology in W₂712 working face of Xiaoqing Coal Mine, it proves that the supprot strength and fracture space of withdrawal roadway can meet the needs of production, can improve the recovery rate, effectively reduce the equipment occupation time, and provide the necessary guarantee for safety, efficient work of mining face.
