Abstract: Based on the analysis of the design of the parameters of medium-deep hole blasting, this paper explored the practical
application of medium-deep hole blasting technology. The results show that the application of medium-deep hole blasting
technology can not only ensure the quality of roadway forming, but also accelerate the speed of roadway excavation, which has a
positive impact on improving mine production efficiency.

Key words: coal mine; driving of rock roadway; medium-deep hole blasting; parameter design
