Study on the influence of slit structure on safe and efficient directional fracture blasting effect.
Tian Y, Zhang Y, Lin H, Chi E. Tian Y, et al. Sci Rep. 2023 Oct 10;13(1):17063. doi: 10.1038/s41598-023-43814-3. Sci Rep. 2023. PMID: 37816860 Free PMC article.
When the slit angle is 20, the energy accumulation and loss reduction effect of strip slit charge blasting are the largest, the distribution of blasting cracks is the best, and the directional fracture blasting effect of slit charge is the best. ...Compared with the …

Design method of blasthole charge structure based on lithology distribution.
Chen Y, Chen J, Wang P, Zhou M, Yang H, Li J. Chen Y, et al. Sci Rep. 2021 Dec 20;11(1):24247. doi: 10.1038/s41598-021-03758-y. Sci Rep. 2021. PMID: 34930974 Free PMC article.
The density of geological exploration boreholes is one of the main bases for blasthole charge structure design. Due to the low density of geological exploration boreholes, it is impossible to obtain the blast hole rock formations' distribution accurately. ... …
