| Abstract: | The application of hole-by-hole blasting technique is not common in underground gold mining in China.The paper explains the choice and design of time interval and detonating network of hole-by-hole blasting. The industrial experiment and practice of hole-by-hole millisecond blasting in Nalin gold mine is introduced.It is found that the long and medium hole drilling hole-by-hole blasting can reduce the blasting concussion,enhance the blasting effects and safety. |
