Abstract: In view of the serious imbalance of mining ratio in coal mining enterprises, the shortage of mining replacement and the loss of personnel, track dip roadway (lower section) in Ⅱ63 mining area of Hengyuan coal mine an average of 3.0m per day, slow operation efficiency, long drilling and rock loading time, which seriously affects the speed of roadway excavation. It is proposed that through the introduction of advanced supporting equipment, the mechanized working line of the excavator loader supported by the hydraulic tunneling trolley is formed, which realizes the integrated rapid tunneling operation mode of drilling, rock loading and transportation, and the daily single advance is gradually increased by 4.7m However, there is still a certain gap between the blasting hole loading and the theoretical working efficiency, which provides certain basis and reference for the optimization and improvement of the mechanized working line of the rock roadway and the management of on-site labor organization.
