THROWING AND SLIDING EFFECTS IN DIRECTIONAL BLASTING FOR BUILDING A DAM

The key problem in building a dam by directional blasting is the calculation of throwing and stack. The mechanical processes of throwing and stack are analysed in this paper. On the basis of some large native directional blasting works, the author summarized some empirical laws such as the geometrical relations of the central longitudinal section of the dam, the throwing distance, the delay ignition time, the crater formation and the sliding effect, especially the author suggests a method similar to that of energy integration in hydrodynamics to estimate the sliding distance.The conclusion is that the throwing and sliding effects must be equally considered in directional blasting for the dam building.
