| Abstract: | The base of transmission of 1~# ball mill at Sanshimudi concentrator come into beingcranny. In the demolition blasting the detonator quantity and disposing orifice parameter was adjusted by blasting test, which made detonator consumption and dispose orifice reasonable, and gasleakage was avoided by taking some technical measures. At the same time, shaking endangermentspread under special condition was discussed. |
