| Abstract: | Through theorical analysis and laboratory model tests, the optimum blasting parameters ofmillisecond blasting for rock drifting have been gotten. A new millisecond electric detonator has been developed and it was proved by site commecialr test. Therefore, the utilization of boreholes increases by 7. 8%and the charging time is shortened by 20- 30%. |
