Abstract: During the construction of the subway, the explosion control technology is essential, vertical blasting technology can improve the utilization rate of the cannon, and extend the time of explosion, reduce the blasting vibration, which can be effective The protection of the burst surrounding quarrying company buildings and the natural environment can also greatly enhance the construction quality of the subway engineering. Based on this, this paper makes a simple explore to the subway blasting construction process and precautions in accordance with the actual engineering overview, in order to provide reference to relevant personnel, easy to do related controls as much as possible in the later subway blasting construction process, enhance the construction of the subway blasting Safety and quality of construction.
