Abstract: | The lumpiness of rock blasting has direct impact on engineering quality. Based on the earth and rock engineering case of mild slope development program in Lishui ecological industry, a key program of Zhejiang province, the causes and specific reduction methods of boulder yield in mild slope area are analyzed and presented. And good blasting results are obtained. |
