STUDIES ON TWIG CHARGE CAVERN BLASTING

Chen Shihai; Li Yumin; Lin Changmu; Zhao Jinqiao(Shangdong Mining Institute, Taian, Shandong,271019)  
The urgent solving problems of twig shape charge cavern blasting,such as the opti-mum hollow rate,end effect of explosives are presented theoretically in this paper. The refered pa-rameters of twig charge blasting are given,and their accuracy is tested and verified by an example. At the same time,seiamic effect of blasting is discussed by the results of measuring seismicwaves.
