贵州开阳磷矿区环境地质问题浅析

An Environment Geological Impact on the Kaiyang Phosphorous District in the Central Guizhou

本文从矿区开采几十年来，所产生的环境地质灾害的观察，列举山体崩落、塌陷、滑坡泥石流、水均衡的破坏、地表水径流的改变以及水土流失所造成的地质灾害给矿山开拓、人民生命财产所造成的损失，提出了治理这些灾害的几点建议，对正在开拓的矿山有一定的实际意义，同时对于拟开发的矿山的环境地质问题有借鉴作用。

The paper presents a summary of geological hazards, such as avalanche, rock fall, debris flow, spoiled balance between supply and need of water, diversion of surface runoff, and soil erosion, that have taken place and then to a different extent caused tremendous damages to the life, property and mineral production since the phosphorous mines in the Kaiyang area of central Guizhou ran. Moreover, the author has produced quite a few of proposals to control and prediction.Meanwhile, these proposals are considered to be extremely valuable perspectives and of practical guidance for the construction of the near future mines.
