As the first step of mine production, blasting has a vital influence on the safety and smoothness of mine production, the correctness and quality of blade filling and transportation operation, as well as the mine production efficiency. Considering that the effective reduction of detonation velocity and depth is an important scientific research project in the mining industry, given the close relationship between high detonation velocity on the one hand and the size of the base and the quality of the explosion on the other, there are many factors in the process of exposed wing blasting, which lead to the formation of root block and deep block. The related factors of the large block and deep block need to be studied more deeply, effectively and scientifically. 展开更多
