A large tin mine in China has reached a deep stage, in order not to affect the production schedule, it is decided to open up the original extension of the main ramp. Based on the practical engineering geological condition, this paper makes researches on the use of smooth blasting to excavate the main tunnel quickly. It also describes in detail the choice of specific parameters of smooth blasting and method of calculation, tunneling ventilation, roadway timbering, blasting slag, construction management technology. The actual on - side blasting results show this method has a good effect ： rock surface is smooth after blasting, achieving the desired results. Every stage of the construction is smooth and reaches a high level of management.
