甘肃省成县徐明山铅锌矿床工程地质条件特征

Engineering Geological Features of Xumingshan Lead-zinc Mine in Chengxian County

徐明山铅锌矿位于西秦岭山系西南的陇南山区,山势险峻,多悬崖、峡谷,"Ⅴ"字型谷地发育,属中壮年期中高山区,地表水系比较发育,属长江流域嘉陵江水系,为大陆性温带季风气候区。矿区工程地质勘探属于第二类—块状岩类,工程地质勘探的复杂程度划分为第一型—简单型。

The Xumingshan lead-zinc mine is located in Southwest of west Qinling Mountains. steep cliffs,the canyon, ＂Ⅴ＂ word valley development,it is medium-high mountain is in the prime of life. The water systems in this district are well developed,Belong to Jialing river water system in Yangtze river basin,while the climate here belongs to temperate continental monsoon climate zone. The complexity of the exploration of the engineering geology is classified for the second – massive rock class,belonging to a first species-simple.
