According to requirements of gallery drilling of mine tunnel, the paper was studied technical indicators, main struc-ture principles and technical advantages of column drilling machine, and pneumatic column drilling machine. The size and weight of drill were reduced a lot compared to other type drilling machines, which could easily moved only by human and didn't need power supply, which improved safety.
