针对构造煤与原生结构煤分界处的煤体类型不易识别的问题,运用判别分析法,选取构造煤、原生结构煤的测井数据为样本。首先对测井数据进行标准化,再优选测井曲线。通过数据处理来建立分类标准,对待识别的煤层测井采样段进行逐一判别、归类。将该方法运用于山西寺河井田进行构造煤识别。以识别出的各钻孔构造煤数据为基础,利用线性插值法得出该区构造煤分布发育图。经比较与钻孔、巷道揭露的情况基本吻合,验证了该方法的正确性,同时提高了识别构造煤的精度。
Aiming at the problem that the type of coal body at the boundary between structural coal and primary structural coal is not easy to identify, the well logging data of structural coal and primary structural coal are selected as samples by discriminant analysis. First of all, the logging data should be normalized and the well log should be optimized. Through the data processing to establish the classification criteria, to be identified by the coal seam logging sampling section one by one discrimination, classification. This method is applied to the identification of tectonic coal in Shanxi Sihe Minefield. On the basis of the data of identified coal boreholes, the distribution map of tectonic coal distribution in this area was obtained by linear interpolation. The comparison with the borehole and roadway exposing basically coincide, which verifies the correctness of the method and improves the accuracy of identifying tectonic coal.
