原始语种摘要: The proportion of on-site mixed emulsion explosives in mining is getting higher and higher, in order to better use the explosive performance of mixed explosives to improve energy utilization. Based on the wave impedance theory, the wave impedance of mixed explosives is changed to make rocks The wave impedances are matched to achieve the purpose of improving the blasting effect and reducing the bulk rate. After field test, increasing the sensitizer content within a certain range is beneficial to the improvement of explosive performance. When the explosive sensitizer content is 1.15%, the best matching coefficient of mixed explosive and rock impedance is 2.51, the rock after blasting is large. The block rate is reduced and the rock crushing effect is better. After this matching test, it is...
