| Abstract: | In excavation of rock cut,the blasting technology combined chamber blasting with presplit blasting for once through shaping of slopes can be used for well solving the problem on the stability and quality of a slope which is difficult to be solved by use of conventional chamber blasting in the past This technology can effectively improve the blasting effect to dominant rock excavation,without clearing of slope toe and leveling of slope front,thus lowering the cost of the project In this paper,the design method and constructing process are introduced and the mechanics of the combined blasting technology is outlined In addition,the influence of geological discontinuities on blasting effect and the impact of the presplit fissure's width on once through shaping of slopes |
