摘要
本文从煤矿开采活动全过程及各产污环节对整个煤矿区引起的土壤重金属污染诱因进行了系统分析,并提出要深入进行煤矿区土壤环境系统分析,在此基础上加强煤矿区土壤重金属污染评价、合理划分土壤功能区,并运用系统-复合联合模式进行煤矿区土壤修复;基于煤矿开采工程对土壤重金属污染的普遍现象,本文提出在煤矿资源开采全过程实施生态环境工程,充分认识土壤环境系统过程的非线性和结果的不确定性,并实施相应的环境监测以便及时发现和解决问题;确保土壤环境系统在自主性基础上进行恢复,积极探索煤矿区土壤重金属污染治理及生态修复的新方法。
The paper makes researches on soil environment effects of the whole coal-mining area from the production process and various aspects of the pollution, and put forth to in-depth analysis of soil environmental system of coal-mining areas. On the basis, we should reinforce the evaluation of soil contaminant in coal-mining area, reasonably drawn soil function area, and repair soil coal mine by using the system-combined mode; Based on the common soil contaminant phenomenon caused by the coal mining project, the paper raises ecological environment engineering in the process of the implementation of the coal resources mining, and non-linearity of the process of the soil environment system and consequence uncertainty should be cognized and the corresponding environmental monitoring should be implemented to discover and resolve the problem. The main objective is that the soil environment system is insured to base on independence. To achieve our objective, we must Actively explore new methods of soil heavy metal pollution and coal mining areas of ecological restoration.
