| Abstract: | Sublevel subsequent filling with downward deep hole ore blasting mining method was used in 700~900ml in Chambishi Copper Mine. According to the construction of cutting shaft, the deep hole step blasting to form cutting shaft is put forward. Blast hole parameters,charging structure,denotation way are designed and calculated.The practical blasting effects show that,deep hole step blasting has perfect applicability in Chambishi copper mine.So,it can provide some reference for some relative engineering. |
