摘要
本文论述了水垫层在深孔爆破中的作用。通过模型爆破的高速摄影照片和爆破块度分析,阐述了水垫层对爆破过程和爆破效果的影响。在上述结论基础上,在露天矿进行生产爆破试验,并取得了预期的爆破效果。
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.
