贵州开阳磷矿洋水矿区环境地质问题分析

由于开磷矿区地处山区,矿区自然地质条件较差,地表切割强烈,沟谷纵横,加之建矿几十年的矿山开采, 尤其是近十几年来个别乡镇企业对矿山掠夺性开采,矿区引发了一系列的环境地质问题,如山体崩塌,水土大量流失、滑坡、泥石流等地质灾害,本文通过对开阳磷矿洋水矿区环境地质问题及主要成因进行分析,提出因地制宜地采取有效措施控制、防止不良地质现象和地质作用的发生发展,合理地利用环境资源,加快对人为破坏活动的治理,稳步恢复区域生态系统的良性循环,以达到生态的最佳效益。

EVALUATING ENVIROMENTAL GEOLOGY OF YANGSHUI PHOSPHORITE DEPOSIT DISTRICT IN KAIYANG PHOSPHORITE MINE

Kaiyang phosphorite mine lies in mountainous area. Its nature geological conditions is worse, the earth's surface's incise is intensity and the ravine can be found everywhere. The wrosen nature geological conditions and the minging in the past few decades, especally the unrestrained exploitation of the re by some village-and-town enterprise, induced series enviromental geology problems,such as the geologic hazards dilapidation,soil erosion,landslide,mud-rock flow etc. On the basis of analysis the cause that indeced the enviromental geology problems in Yangshui phosphorite deposit district, the paper gives us some suggestions that we must adjust measures to local conditions to control and prevent ruinous geologic function, rational make use of enviromental resource, pick up the harnesing on man-made destruction and resume regional biogeocenose in order to gain the best ecological benefit.
