基于模糊数学法的南四湖地区矿山地质环境现状综合评价

Comprehensive Evaluation on Present Condition of Geological Environment in the Mine in Nansihu Area Based on Fuzzy Mathematics Method

摘要:

南四湖省级自然保护区内煤矿资源丰富，高强度的开采利用给矿山地质环境带来巨大挑战。本文对区内12个煤矿山进行了现状调查、样品采集及测试，分析了地面塌陷、土地资源破坏、地形地貌景观破坏、含水层结构破坏、水土污染等地质环境问题的类型、分布特征、危害程度等基本特征。采用模糊数学法进行矿山地质环境影响程度评价，综合划分评价单元及影响等级，提出治理建议，为开展矿山地质环境保护与矿山地质环境问题治理工作提供依据。

Abstract:

Nansihu Provincial Nature Reserve is rich in coal mineral resources. High-intensity mining and utilization has brought great challenges to geological environment in the mine. In this paper, present condition, sample collection and test of 12 coal mines have been carried out. The types, distribution characteristics, harm degree of ground collapse, land resources destruction, landform and landscape destruction, aquifer structure damage and water and soil pollution have been analyzed. By using the fuzzy mathematics method, the impact degree of geological environment in the mine have been evaluated, the evaluation unit and impact level have been divided and evaluated comprehensively, and treatment suggestions have been put forward. It will provide the basis for the protection and treatment of geological environment in the mine.
