| Abstract: | The geological conditions of Muzigou tailings dam site are complicated.To achieve good performance of directional blasting,the blasting chamber design is optimized,and the suitable blasting parameters and suitable blasting sequence of multistage short delay detonation are selected.Then,once blasting has achieved 490 000 m3 earth and stone blasted of which 63% is stockpiled on dam.The flying stones,vibration strength and blasting damage range are effectively controlled. |
