| 中文摘要: |
| 该铅锌矿位于贵州省南部，属于典型的喀斯特地形地貌，矿体埋深500 m以内，围岩主要为灰岩、白云岩。对矿山建设及生产构成威胁的主要因素为断层裂隙、富水区块、不稳定岩体等，本文通过使用音频大地电磁法(AMT)、瞬变电磁法、高密度电法三种物探测量方法进行地表和井巷测量，结合地质钻孔、建设巷道等已知条件，对矿山建设生产提供长期的跟踪和服务工作，总结了从面到线、从线到点的超前预报方法，较好地指导了矿山建设和生产工作，该方法具有一定的推广意义，能够为掌子面开挖、井中灾害预报等提供较为客观的评价依据。 |

| The lead-zinc mine is located in the southern Guizhou，belonging to the typical karst landformThe ore body is buried within 500 meters，and the surrounding rock is mainly limestone and dolomiteThe main factors which threat to the construction and production of the mine are fault cracks，water-rich blocks，unstable rock masses and so onIn this article，it uses three geophysical survey methods，audio magnetotelluric method(AMT)，transient electromagnetic method，and high-density electrical method，for surface and shaft measurement，combined with known conditions such as geological drilling and construction tunnels，to provide long-term tracking and service work for mine construction and productionIt summarizes the all side advanced prediction method，which guides the mine construction and production work effectivelyThis method has certain generalization significance and can provide more objective evaluation basis for face excavation，shaft disaster prediction，etc |
