都兰察汗乌苏石料矿山环境地质分析及生态修复治理

Environmental geological analysis and ecological restoration treatment of Chahanwusu stone mine in Dulan

矿山在进行生产作业时难免会产生各种各样的环境地质问题,对周围的环境造成严重的影响,尤其是露天开采的作业方式,对环境的破坏性更为明显。以都兰察汗乌苏建筑用石料矿矿山为研究对象,对矿山目前存在的环境地质问题进行分析,并开展相应的治理措施探讨。研究结果表明,矿山当前存在的主要环境地质问题为发育有若干不稳定采矿边坡,存在含水层、土地资源、地形地貌景观破坏等。因此,针对上述存在的环境地质问题提出了7种治理措施,分别为危岩体及碎石清理、边坡的削坡反压、排水沟建设、场地回填平整、网围栏与警示牌工程、覆土工程和植被重建工程。该讨论内容可能对类似矿山环境地质问题治理具有一定的理论与实际意义。

Mines inevitably generate various environmental geological problems when carrying out production operations,which have serious impacts on the surrounding environment,especially the open-pit mining operation,which is more obviously destructive to the environment.The current environmental and geological problems of the mine are analyzed and the corresponding management measures are discussed,taking the Dulan Chahanwusu construction stone mine as the research object.The results of the study show that the main environmental geological problems of the mine are the development of several unstable mining slopes,the phenomenon of water-bearing layers,land resources,topography,and geomorphological destruction.At the same time,seven kinds of treatment measures were proposed for the above environmental geological problems,namely,dangerous rock mass and gravel cleaning,cutting slope and back pressure,drainage ditch construction,site backfill and leveling,net fence and warning sign engineering,earthing and revegetation engineering.The content of this discussion may have some theoretical and practical significance for the management of environmental geological problems in similar mines.
