| Abstract: | Unstable rock chamber blasting is the first blasting scheme for large volume emergency treatment with rapid construction speed. With detailed geological survey and topography mapping, and with informational instruction, the risk-elimination by chamber blasting was carried in Wushan, 287000m^3 unstable rocks were eliminated in 46 days. The paper discussed the blasting scheme design, blasting parameter selection, construction technology and blasting effect with the experience. |
