| Abstract: | Taking the newly constructed Spillway tunnel of a large reservoir in Shanxiprovince as an example, this paper has studied the experimental simulation method and its techniques for the rock plug blasting in mud. On the basis of the model experimental results, an operation scheme for on--site rock plug blasting is worked out. The real rock plug blasting in the tunnel site has tested the correctness of the experimental results. It is the first time nationally and internationally that rock plug blasting in mud has been successfully made. |
