Applicability study on new working line in track descent rock roadway of Qidong coal mine

In order to improve the excavation efficiency of rock roadway in Qidong coal mine and reduce the labor intensity, taking the track descent of second level and three mining area in Qidong coal mine as the research background, by analyzing the influencing factors of the original excavation construction technology of the roadway, optimizing production organization management and construction technology level, the CMJ2-18 crawler double-arm rock drilling jumbo is introduced for rock breaking, and the ZWY-150/55 excavator loader is used for rock loading and transportation with DSJ-80 belt conveyor.It not only improves the efficiency of roadway excavation, but also reduces the labor intensity of workers, improves the working environment, enhances the enthusiasm of workers, and realizes the safe and efficient rapid excavation of rock roadway in Qidong coal mine.
