Abstract：Tang’an Mine is a high gassy mine. A surface gas drainage shaft was located near the mine ventilation shaft industrial square ,was 1 m in diameter and 287 m in depth. The mine gas drainage shaft was constructed with the raise boring machine. A pilot hole was firstly drilled and then was reamed to a diameter of 1 m. The main engineering of the mine gas drainage shaft was consisted with three parts. First was to drill a mine gas drainage shaft with a depth of 287 m and a diameter of 1 m. Second was to install the gas drainage pipeline with a outer diameter of 530 mm and a thickness of 15 mm. Third was to install the gas drainage pipeline with a depth of 1.5 m and a length of 400 m.Due to the scientific and rational construction plan ,a safety and rapid construction was realized for the mine gas drainage shaft.
