摘要
为有效应对四川省白马红格矿区存在的过度开采与无序开采行为,针对常规方法难以对矿山地质环境承载力进行量化分析的不足,根据矿区特殊的自然环境特征,选取了自然地理、社会经济、矿山开发、矿山环境、基础地质5个要素层共14个指标构建了矿区地质环境承载力评价指标体系,采用定性与定量相结合的综合评价法-层次分析法(Analytic Hierarchy Process,AHP)进行了矿区地质环境承载力评价。研究表明:矿区承载力存在明显的高低分布和空间发展规律,根据承载力高低可将矿区划分为优等区、中等区、差等区,绘制了矿区地质环境承载力分布图,并对各区的空间分布特征进行了分析,认为白马红格矿区承载力整体较低,中等区与差等区面积总和为615.73 km^2,占矿区总面积的28%,差等区面积达到79.25 km^2,占矿区总面积的3.6%,研究结果实现了对矿区地质环境承载力定性与定量的综合评价,可有效反映矿区地质环境承载力状况。在上述分析的基础上,针对矿区承载力差等区,提出了优化矿区周边环境、开展生态修复工程、建设绿色矿山等措施,对于提升整个矿区的地质环境承载力、实现矿区可持续发展、遏制矿区存在的不合理开采行为有一定的参考价值。
In order to effectively deal with the unreasonable mining activities such as over- exploitation and disorderly mining in Baimahongge mining area in Sichuan Province,aiming at the insufficiency of the conventional methods that are difficult to carry on the quantification analysis of the mine geological environmental bearing capacity,combined with the special natural environment characteristics of the mining area,14 indexes including physical geography,social economy,mine development,mine environment and basic geology are selected.The evaluation index system of geological environmental bearing capacity of the mining area is established,and the comprehensive evaluation method-analytic hierarchy process(AHP)that combines qualitative and quantitative methods evaluation ideas is used to evaluate the geological environmental bearing capacity of the mining area.The study results show that high-low distribution and spatial development regularities of the mining area are obvious,according to the bearing capacity,the mining area can be divided into excellent,medium and poor areas.The distribution map of the bearing capacity of the geological environment of the mining area is drawn,and the spatial distribution characteristics of each area are analyzed.It is concluded that the bearing capacity of Baimahongge mining area is low as a whole,and the total area of medium and poor areas is 615.73 km2,accounting for 28% of the total area of the mining area,and the area of the poor area is 79.25 km2,accounting for 3.6% of the total area of the mining area.The study results have realized the comprehensive evaluation of the bearing capacity of the geological environment of the mining area qualitatively and quantitatively, which can reflect the bearing capacity of the geological environment of the mining area more truly and effectively.Based on the above discussion results,in view of the poor bearing capacity of the mining area,some countermeasures are put forward,such as optimizing the surrounding environment of the mining area,implementing the construction of ecological rehabilitation projects and building green mines,which are of certain reference value for enhancing the bearing capacity of the geological environment of the whole mining area,realizing the sustainable development of the mining area and curbing unseasonable mining activities of the mining area.
