| Abstract: | This paper introduced the study and treatment of high step burst body which took place in the early days of changing underground into opencast lnining in Zijinshan Gold Mine.It emphasized theoretically and practically that the opencast mining was faced with the threaten of undergroundmined out area thus the coordination between mining and stripping was quite important.The technical measures to eliminate and control the harm of high step burst body were also described. |
