【摘要】：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。
[Abstract]:In order to solve the problem that it is difficult to describe the bearing capacity of mine geological environment effectively by conventional methods, taking the Wulonggou gold mine area as an example, the spatial statistical analysis method is used to evaluate the bearing capacity of mine geological environment. Firstly, the evaluation index system of the bearing capacity of mine geological environment is established, which covers 15 indexes, such as social economy, mine development, physical geography, basic geology and mine environment, etc. The classification standard of each index is set up and the weight of each index is determined. Then the evaluation value of each index is used to calculate the geological bearing capacity of the mine. Finally, the hot spot analysis method and the high and low cluster analysis method are used respectively. The geological bearing capacity of the mining area is further evaluated by density analysis and other spatial statistical methods. The evaluation results are consistent with the results of the field geological survey in the mining area and have certain reference value for realizing the coordinated and sustainable development of the safe mining and ecological environment in the mining area.
