根据矿山地质环境变异类型及趋势,选取地质背景、地质灾害、水土环境破坏、矿产开发和水文植被5要素构建矿区地质环境质量综合评价指标体系,从中选取25个指标作为矿山地质环境质量预测评价因子,构建经典域物元和节域物元,将可拓聚类预测方法应用到矿山地质环境质量预测评价中。以云南省昭通市毛坪铅锌矿为例,对矿山开采5 a后的地质环境质量进行预测评价。结果表明,可拓聚类预测通过变量控制物元变化,可根据需要用不同的方法确定变量以构造各样本经典域和节域物元,评价结果符合实际。
According to the types and trends of variation of geologic environment in mines, we select the five indexes of geo-environmental quality in mining area, including geological background, geological disasters, soil and water environmental destruction, mineral exploitation and hydrological vegetation, and select 25 indicators as the prediction and evaluation factors of mine geological environment quality , Constructing the classical domain matter element and section object matter element, and applying the extension clustering prediction method to the prediction and evaluation of mine geological environment quality. Taking Maoping Pb - Zn deposit in Zhaotong City, Yunnan Province as an example, the geological environment quality after 5 years of mining is predicted and evaluated. The results show that the extenics clustering predicts that the variables can be controlled by variable control, and variables can be determined by different methods to construct the classical and section matter-objects of each sample. The evaluation results are in line with the actual situation.
