Abstract: Improving ventilation efficiency is one of mining safety measures, and High efficient drilling technology for mining area by raise boring machine is significant method. Ventilation shaft arrangement and anti-well drilling capacity is analyzed for the characteristics of western stratum. The idea about achieving the function of large diameter shaft ventilation by air dual shaft. Mine shaft rising boring technology of air dual shaft is proposed in order to avoid close-range shaft accident. The specific construction process is complete two guide holes firstly, expand drilling afterwards. The reinforcement measures such as grouting should be done when guide hole is drilling. The good effects of technology is proved by air dual shaft construction in Sihe coal mine.
