唐山露天煤矿集中区地质环境质量评价体系构建

为了更好地治理和修复矿区地质环境，减少资源消耗，以唐山开滦煤矿集中区作为研究对象，构建了唐山露天煤矿集中区地质环境质量评价体系。该煤矿集中区位于河北省唐山市境内，以中厚煤层为主，根据矿区的综合影响程度，明确整体地质环境，挑选开滦煤矿集中区地质环境数据中的评价因子，建立多层次和多阶段评价体系模型，计算关联系数和数列；根据各指标对地质环境质量的贡献大小确定权重，实现评价体系的构建。经过分析检验，评价体系内各项指标均能够反映开滦煤矿集中区地质环境影响程度，具有较好的分类效果；通过构建的评价体系能够准确了解开滦煤矿集中区的地质环境情况，便于后期及时治理修复破坏区域。

Construction of geological environment quality evaluation system in Tangshan open-pit coal mine

In order to better control and repair the geological environment of the mining areaS and reduce the consumption of resources，this paper takes the Kailuan Coal Mine concentration area in Tangshan as the research object，and constructs the geological environment quality evaluation system of Tangshan open-pit coal mine concentration area.This coal mine concentration area is located in Tangshan City，Hebei Province，dominated by medium thick coal seam.According to the comprehensive impact degree of the mining area，along with clarifying the overall geological environment，the evaluation factors in the geological environment data of the Kailuan open-pit coal mine concentration area are selected，the multi-level and multi-stage evaluation system model is established，the correlation coefficient and number sequence are calculated，and the weight is determined according to the contribution of each index to the geological environment quality to achieve the construction of the evaluation system.After analysis and inspection，all indexes in the evaluation system can reflect the degree of influence of geological environment in the Kailuan Coal Mine concentration area，with good classification effect.The constructed evaluation system can accurately understand the geological environment in the Kailuan Coal Mine concentration area，which is convenient for the late timely treatment and restoration of the damaged area.
