摘　　要：凡口铅锌矿山隐伏岩溶发育,地下水径流带易发育岩溶管道,地面塌陷活动频繁、生态破坏严重。岩溶管道基本位于逆冲断裂F203的上盘,受构造控制作用明显,在背斜轴部尤为发育。研究发现岩溶管道的分布与岩溶发育程度呈正相关关系,方向以东西向、北西向为主。多源示踪试验证实岩溶管道呈树枝状,集中径流带两侧交错发育低角度支流,存在明显的分支、复合现象。岩溶管道内,地下水径流速度186~546m/h,径流量9151 m^(3)/d。研究结果可为矿山工程建设、环境保护提供科学依据。Fankou lead-zinc mine exists developed covered karst and karst pipelines is easy to develop in the groundwater runoff zone,wbioh resulted to Land collapse occur red frequently,ecological destroyed seriously.These karst pipelines are primarily located in the hanging wall of the reverse fault F203,obviously controlled by structure,especially developed in the anticlinal axis.The distribution of karst pipelines shows a positive correla-tion with the degree of karst development,predominantly trending in the east-west and northwest directions.Multi-source tracer test showed karst pipelines exhibit a branching pattern,with low-angle tributaries developing on both sides of the concentrated flow zone.There is a distinct presence of branching and compounding phenomena.In karst pipelines,the velocity of water flow is 186-546 m/h and runoff volume is 9151 m^(3)/d.The research results can provide a scientific basis for mining engineering construction and environmental protection.
