| Abstract: | This paper describes the effects of bottom water cushion on long hole blasting. By analyses of the pictures taken by high-speed photography and the average lumpiness of fragments of models after blasting, the effects of bottom water cushion on the process and efficacy of blasting have been expounded. Based on the above results, practical blasting tests have been carried out in open-pit mines and the expected results have been got. |
