五龙沟矿山地质环境承载力评价的空间统计分析法

为解决常规方法难以对矿山地质环境承载力进行有效描述的问题,以五龙沟金矿区为例,采用空间统计分析法进行矿山地质环境承载力评价。首先建立了涵盖社会经济、矿山开发、自然地理、基础地质和矿山环境等方面共15个指标的矿山地质环境承载力评价指标体系,设置了各指标的分级标准并确定了各指标的权重;然后利用各指标的评价分值对矿山地质承载力进行计算;最后分别采用热点分析法、高低聚类分析法、密度分析法等空间统计分析法对该矿区的地质承载力进行了进一步评价。评价结果与矿区野外地质调查成果较一致,对于实现该矿区安全开采与生态环境协调可持续发展有一定的参考价值。

Evaluation of Geo-environmental Carrying Capacity of Wulonggou Mine Based on Spatial Statistical Analysis Method

The mine geo-environmental carrying capacity evaluation results of conventional fixed formula is incomplete and inaccurate,and the space condition is difficult to describe the mine geo-environmental carrying capacity. In order to solve the above problems existed in the evaluation of mine geo-environmental carrying capacity evaluation, taking Wulonggou gold mining area as the study example,the spatial statistic analysis method is used to conduct geo-environmental carrying capacity e-valuation of the mine. Firstly,the 15 indicators are selected from the aspects of social economy,mining,natural geography,basic geology and mine environment to establish the geo-environmental carrying capacity evaluation indicator system of Wulonggou mining area,and the classification standard of the above 15 indicators is established and the weight values of them are also de-termined;then,the score value of the above 15 indicators are used to evaluate the geo-environmental carrying capacity of the mining area;finally,the geo-environmental carrying capacity of the mining area is further evaluated by using the spatial statisti-cal analysis methods (hot spot analysis method,high and low clustering analysis method and density analysis method). The study results of this paper is basically consistence with the actual geological investigation results,and it has some reference for promoting the sustainable development of safety mining and ecological environment.
