济宁市嘉祥县石灰岩矿山地质环境评价与治理

在对嘉祥县石灰岩矿进行地质灾害危险性评估、矿山环境地质问题评价的基础上,建立了一套评价体系,其中地质灾害危险性评估分为2个评价指标,矿山环境地质问题评价分为2种要素3个指标,同时将矿山恢复治理难易程度也作为一个评价因子。评价过程中对各指标危害性大、中、小程度均单独赋值,然后将各指标的分值进行叠加,确定出矿山环境地质问题的等级,将概划出的13个评价单元分为极差、差、一般3个区。提出了强化矿山管理、植树造林、科学避让、修建拦水坝等保护与治理措施及建议。

Evaluation and Management of Geological Environment in Limestone Mine in Jiaxiang County of Shandong Province

On the basis of danger degree evaluation of geological hazards and geological environment evaluation of mines in Jiaxiang limestone deposit,a set of evaluation system is set up.Geological hazards evaluation is divided into 2 evaluation ratios,and mine environment evaluation is divided into 2 elements and 3 ratios.At the same time,easy or diffcult to manage mines is also regarded as an evaluation factor.During evaluation,the point value of each index is accumulated to determine the degree of environmental problem.Then,13 evaluation units can be divided into worse area,bad area and common area.Some protection countermeasures,such as strengthening mine management,forest plantation,avoding scientifically and building dam are put forward in this paper.
