Based on the achieved engineering practice results of deep roadway drivage in Xinwen Mining Area, aimed at drivage problem of deep cross-level coal-rock, EBZ-135 fully-excavating machine had been used to replace traditional roadway blasting drivage, corresponding key technology of fast supporting for deep large sections of coal-rock roadway in high stress had been proposed, and latter mating transport system transformation of fully-mechanized fast drivage technology had been cooperated, which formed a suit of fully-mechanized fast drivage technology for deep large sections of coal-rock roadway in high stress. The application results show that the fully-mechanized fast drivage technology can markedly enhance the whole shaping quality of roadway, improve drivage efficiency and cycling footage immensely, reduce roadway drivage cost, and the good result of average month footage at 300 m and maximum month footage at 360 m have been achieved finally.
