综合模糊评价法在矿山地质环境影响评估中的应用——以贵州瓮福磷矿区小坝矿段为例

Application of Comprehensive Fuzzy Evaluation Method in Mine Geological Environment Impact Assessment——Taking Wengfu Phosphate Xiaoba Mine as an Example

瓮福磷矿区小坝矿段位于贵州省福泉市北西部。矿山开采时间长,强度大,引发地质灾害、地形地貌景观破坏及含水层破坏等矿山地质环境问题多,主要表现为地面塌陷、崩塌、滑坡、泥石流;土地植被资源占压与损毁;矿区及区域地下水位下降、井泉流量减小甚至干枯、地表水体漏失、水质恶化等。利用综合模糊评价原理,根据规范要求,结合小坝矿段具体的地质环境问题,作出矿山地质环境影响严重、较严重和较轻的评估结果,并将小坝矿段划分地质环境严重、较严重区各1个,较轻区2个。

Wengfu Phosphate Xiaoba Mine is located in northwestern of FUQUAN, GUIZHOU.The mining time is long, high strength,lead to geological disasters,landform and landscape destruction and aquifer destruction of mine geological environment problems,mainly for ground subsidence,collapse,landslide and debris flow;land resources and vegetation encroachment damage; groundwater level decline, mining area and well flow is reduced or even dry, surface waeer leakage, the deterioration of water quality,etc.By using the fuzzy comprehensive evaluation principle,according to the specification requirements,combined with the small dam mine specific geological environment problems,this paper made the mine geological environment impact is serious,serious and lighter assessment results,and the small dam,mine geological environment seriously divided serious District 1, District 2 lighter.
