摘要:
采用数值模型与理论计算相结合的方法，对某露天采石场爆破开采作业中的单孔爆破、双孔爆破以及多孔爆破进行研究，并进行了现场试验验证。结果表明：同等TNT当量下，双孔爆破时的有效爆破半径比单孔爆破时大53.04%；双排矩形炮孔爆破时的有效爆破面积比双排三角形炮孔时大3.11%。提出了露天采石场爆破开采时双炮孔布置、多炮孔双排矩形炮孔布置以√3/2倍孔距的多炮孔双排三角形炮孔布置的优化措施。
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 √3/2 hole spacing of multi-blast holes, were put forward.
