| Abstract: | Based on the field blasting experiments and construction of the Lijiaxia Hydropower Station, researches are made on the presplit blasting,deep-hole blasting and parameter optimiza-tion of cushion hole,charging structure of explosive and igniter network. The results presented in this paper may be used as reference for other projects. Moreover, researches and pratice on exca-vation of protective layer on extensive horizontal. Foundation surface by one process of blasting are expounded. |
