摘要: 以山西A 矿开采的3 号煤层采掘活动已揭露的小断层资料为基础,选取断层落差、倾角、延伸长度3 个参数,
通过多线性回归方法构建NW、NE 2个方向的断层延伸长度预本构模型,并进行现场应用。结果表明,构建的小断层预
测模型预测的小断层延伸长度的准确率在90%以上,可以为后续揭露小断层延伸长度的确定提供可靠的参数指导。

Abstract: Based on the data of small faults exposed by the mining activities of No.3 coal seam in Shanxi A Coal Mine, this paper
selected three parameters of fault throw, dip angle and extension length, constructed a pre-constitutive model of fault extension
length in NW and NE directions through multi-linear regression method, and applied it in the field. The results show that the
accuracy of the prediction model of the small fault is more than 90%, which can provide reliable parameter guidance for the
determination of the extension length of the subsequent exposed small faults.
