鹤庆北衙铁金矿区环境地质现状及预测评价

THE ENVIRONMENT GEOLOGY AND PREDICTIVE ASSESSMENT OF BEIYA FE-AU OREFIELD IN HEQING

北衙铁金矿区万硐山矿段已露天开采多年,而进入后期,将转入深部地下开采。矿区存在的环境地质问题已初步显现。对露天转地下深部开采时主要的环境地质问题进行预测。

The Wandongshan ore block of Beiya Fe orefield has been opencast for many years.It has also been mined underground by the clino-shaft WXJ1 before.The opencast mining is in the late period.Afterwards,the underground mining in the deep part will begin.The problem of environment geology has begun to appear.We put forward a prognosis of the problem of environment geology in the transformation from opencast mining to underground mining in the deep part.
