| Abstract: | The pre-splitting demolition parameter optimization in the final slope with the crevasse growth of Jiangxi Jinlong Corporation Strip Mine is investigated. The results show that while the pre-hiatus aperture 100mm, depth of hole about 20m, pitch of holes 1.0m and average line charge density 0.445kg/m, the half porosity is still attainable about 60 %. The ideal blasting effect is achieved with the pre-hiatus cushion pitch of holes 1.5m and the pre-hiatus and cushion pitch of holes 1.3m. |
