矿井小断层延伸长度定量化预测在麻黄井田的应用

Application of Extended Length Quantitative Prediction of Mine Minor Fault in Mahuang Field

麻黄井田内9#煤层开采过程中,受小断层影响较大。通过分析断层的落差、倾角、走向与走向长度之间的相关性,采用多元线性回归的方法,分别建立SE向和NE向的断层延伸长度回归模型。回归模型可以为麻黄井田内的小断层延伸长度提供可靠的预测。

In the exploitation process of the ninth stratum in Mahuang field, the work is affected much more by the minor fault. Adopted MLR method through analyzing the correlation among the head, angle and trend length of the fault, and the fault extended length regression models are built at SE and NE directions. The reliable prediction can be provided by the regression model for the minor fault extended length inside of the Mahuang field.
