Study on optimization of roadway support parameters in No.5107 Face of Yongming Coal Mine
Aiming at the support problems existing in the actual production process of No.5107 Face open-off cut in Yongming Coal Mine,through analyzing and studying the causes of these problems,the corresponding optimization measures were formulated,and the support parameters of the optimization scheme were calculated.The final practice showed that the support optimization scheme designed in this paper had a good effect,which could meet the requirements of Yongming coal mine safety production,and significantly improve the construction efficiency and support effect,and provide technical experience for the subsequent rapid excavation construction of Yongming coal mine.
