Abstract: Based on the current situation of rock roadway fully-mechanized tunneling in longgu coal mine, the quantitative analysis is done for the influence factors of the fully-mechanized tunneling by using analytic hierarchy process, finally the tunneling progress is determined by tunneling and support equipments, surrounding rock and temperature. According to key influencing factors, the paper creatively takes the tunneling engineering as a composite system including man, machine and environment to study and find out the best combination of the three, especially the equipment factor, the trinity hydraulic auxiliary rock-breaking new technology provides a strong basis for safety and quick tunneling of large sections of the rock roadway and the scientific decision.
