| Abstract: |
| Effects of the frequently-used design scheme of tunneling blasting are very unsatisfactory when the mine is deep exploited and encountering the granodiorite in laneway tunnelling. Through many field test studies, the blasting design scheme was adjusted and optimized, efficiently crossing this section of granodiorite, which not only improved the design of driving blasting, but also ensured the project completing timely quality and quantity, and even provided a good reference for driving blasting construction of similar rock mass. |
