Abstract: Daliuta coal mine creatively developed high efficient full face tunnel drivage machine and ancillary equipment, reformed the tunneling technology system, and improved the tunneling efficiency, at the same time efficiency has. But high efficiency face a variety of problems in the application process middle, restricted the further development of fast driving system, for example, bolter end top air safety, transportation system, blocking the lump step type self advancing tail walking deviation problem, ventilation and dust removal system optimization problem. Solving these problems have important meaning to further improve the rapid excavation system efficiency and practicability.

Key words: High-speed drivage, Excavation and supporting parallel operation, Continuous transportation, Long short pumping pressure
