| Abstract: | The fragmental degree under bench blasting is measured with the photographic method at the Haizhou opencut coal nine.With the aid of the testing data,the authors give the distribution laws on the fragmental degree for two kinds of rocks using the curve regression in this paper.The results obtained are important to controlling the fragmental quality under bench blasting. |
