矿山地质环境地形地貌景观现状评估量化分级——以陕西省两个煤矿为例

Quantitative grading of status evaluation of landforms and landscape in mining geo-environments: A case study of two coal mines in Shaanxi Province

矿山地质环境保护与恢复治理方案编制规范对地形地貌景观影响程度提出的评估指标在实际工作中存在着不确定性和难以操作、量化的问题。以陕西省彬县和神木县的两个煤矿为例,从场地建设和采煤引发的地面塌陷两个因子考虑,分别对规范中两个指标的影响程度提出了量化分级的数值区间。这套评估指标量化体系,为煤矿矿山地质环境保护与恢复治理方案报告的编制工作提出了可操作性较强的理论依据。

There are problems of uncertainty and difficulties to operate and quantify in practical work in evaluation index about the influence degree of landforms and landscape proposed by compiling code on the project of mining geo-environmental protection and integrated renovation. A case was studied in two coalmines in Bin and Shenmu countries from site construction and ground collapse caused by mining, the numerical intervals of classified quan-tification respectively about the influence degree of two indexes in the standard was put forward. This set of quan-titative system of evaluation index put forward the theoretical basis with strong maneuverability for compiling the project of mining geo-environmental protection and integrated renovation in .coal mines.
