QUANTITATIVE EVALUATION ON GEOLOGICAL STRUCTURE COMPLEXITY OF CUIJIAZHAI MINE,HEBEI PROVINCE
-
摘要: 地质构造复杂程度定量评价是当前矿井地质工作的研究热点之一,其关键技术体现在评价指标和评价数学模型两方面。在地质分析和勘探资料处理的基础上,选取5个非连续性变形参数和5个连续性变形参数,作为地质构造复杂性评价的指标,分别采用统计综合评价和模糊综合评价数学模型,对冀西北蔚县矿区崔家寨井田主采煤层的构造复杂程度进行定量评价,取得良好效果。对比分析表明,两种评价模型在矿井构造复杂程度定量评价方面各有优劣,比较而言,模糊综合评价模型更加客观合理。Abstract: The quantitative evaluation on geological structure complexity is one of the hotspots in the research of mining geology,the key techniques of which include selecting proper assessment indexes and assessment models.On the basis of analysis of geological setting and procession of exploration data,5 continuous deformation parameters and 5 discontinuous deformation parameters are taken as indexes for the evaluation on geological structure complexity.The comprehensive statistical assessment model and comprehensive fuzzy assessment model are both adapted for the quantitative evaluation on geological structure complexity of Cuijiazhai mine,Hebei Province.A comparative study shows that both can be used for quantitative evaluation on geological structure complexity,with the fuzzy model being more plausible.
