| Abstract: | The method for calculating pre-splitting blasting parameters was modified through substantive experiment study and theoretical analysis. The obtained reasonable experimental parameters were validated in fieldwork,achieving a 45% increase of presplitting blasthole spacing and a good presplitting blasting effect, which effectively solved the vibration effect problem in the intensive blasting of the east side of Gushan mining area. |
