| Abstract: | Single-hole blasting, double-hole blasting and multi-hole blasting in the blasting mining operation of an open-pit quarry were studied using a combination of numerical models and theoretical calculations, and the field test verification was carried out. Results show that, under the same TNT equivalent, the effective blasting radius in double-hole blasting is 53.04% larger than that in single-holes blasting, and the effective blasting area in double-row rectangular hole blasting is 3.11% larger than that in double-row triangular hole blasting. The optimization measures for blasting mining in open-pit quarry, including double blast hole arrangement, double-rows rectangular blast hole arrangement of multi-blast holes, and double-row triangular blast hole arrangement with √ |
