Despite the availability of established, sophisticated methods for planning and designing stable slopes in rock, comparatively little attention is usually paid to the problems of carrying out the excavation. Blasting should be carefully planned to obtain optimum fragmentation as well as steep, stable pit walls for a minimum stripping ratio. The principal difficulty facing a blast designer is the lack of prior information about the many critical blasting characteristics of the rock mass. The common practice of trial-and-error blasting will eventually lead to a suitable design, but this must be repeated time after time in variable geology. This frequently results in many. blast damaged slopes with decreased stability and increased safety hazards. Recent research indicates that monitoring drill performance will yield a Rock Quality Index for the rock mass which correlates to a Powder Factor value. Without the costs of additional equipment or personnel, the drilling can provide a continual supply of data, reflecting changes in the rock which enables the selection of an economical Powder Factor, The ultimate goals of this simple correlation system are optimization of fragmentation, elimination of unacceptable blast damage, preservation of inherent rock strength, and maximization of slope stability.

尽管设计稳定的岩石边坡已有成熟的方法,但人们对于开挖过程中的问题通常不够注意,爆破应经过精心的设计,以取得最佳的破碎效果和稳定的边坡,从而得到最低的采剥比。爆破设计人员所面临的主要困难是缺乏有关岩体影响爆破性能的资料。试凑法爆破最终取得合适的设计,但必须在不同的地质条件下反复试验。爆破常常损坏边坡稳定而出现事故。近来的研究指出,观测钻孔效率可以得出与单位炸药消耗量相关的岩石品质指数(Rock Quality index)。不需要增添设备和人员的费用,钻孔工作就能连续不断地提供反映出岩石变化从而可以选择经济的单位炸药消耗量的数据。这一简单的相关体系的最终目的,是优化破碎效果,消除不容许的爆破破坏,保持岩体原有强度并得到最大的边坡稳定性。

Increasing limestone lump rate by blasting is one of research tasks all along. Based on the blasting diagnosis at Xigou Limestone Mine of Jiuquan Iron & Steel Co., this paper points out that at present problems in bench deep-hole blasting limestone open-pit mine everywherel describes the blasting principles for increasing limestone lump rate by bottom broken charge blasting technology. The test of small-scale bench model made from cement grout had been produced. The bottom broken charge blasting technology was used in Xigou Limestone Mine and the little overdepth (or not overdepth blasting) was realized. By this way, the single-hole sequience igniting was gone so that the squeeing action between ore and rock was decreased, the limestone lump rate was increased and the powder factor was decreased.
