Abstract
Establishing a calculation model for parallel cut blasting effect has certain practical significance for guiding tunnel blasting construction. A calculation model of cutting blasting effect is established based on the theoretical analysis in this paper. Under certain conditions, the quantitative relationship between the cutting efficiency and the hole diameter, the depth of the cut hole and the hole distance between the cut hole and the empty hole is obtained. The calculation results of the model are consistent with the results of a pure cutting test, which shows that the calculation model is reasonable.
