废弃矿井地下空间资源开发利用评价指标体系研究

Study on evaluation index system of underground space resources development and utilization in abandoned mines

废弃矿井数量的日益增加,大量地下空间资源被闲置,“双碳”目标背景下对其开发利用迫在眉睫,为此开展地下空间资源开发利用评价指标体系研究。运用层次分析法,通过对开发利用指标的筛选,建立了4大类、13个小类指标的废弃矿井地下空间资源评价指标体系。以山西省白家庄矿为例,通过专家打分法对指标权重进行确定与分析,得到废弃矿井地下空间资源开发利用评价体系的层次结构模型、指标层指标权重分布和准则层指标权重分布,系统分析各指标对开发利用的影响,提出相应开发利用建议,对地下空间资源开发利用方向研究具有参考借鉴意义。

With the increasing number of abandoned mines, a large number of underground space resources are idle. It is urgent to develop and utilize them under the background of “ double carbon” target. Therefore, the research on the evaluation index system of underground space resources development and utilization is carried out. Use the analytic hierarchy process, through the screening of development and utilization indicators, an evaluation index system of abandoned mine underground space resources with 4 categories and 13 sub categories of indicators is established. Taking Baijiazhuang mine in Shanxi Province as an example, through the expert scoring method to determine and analyze the index weight, the hierarchical structure model, index layer index weight distribution and criterion layer index weight distribution of the evaluation system for the development and utilization of underground space resources in abandoned mines are obtained. The impact of each index on the development and utilization is systematically analyzed, and the corresponding development and utilization suggestions are put forward, which has reference significance for the research on the development and utilization of underground space resources.
