摘　　要：矿井小断层普遍存在且错综复杂,对煤层开采影响很大。根据黄河北煤田赵官井田7号煤层小断层资料,选取断层走向延展长度、断层落差和断层倾角3个因素,运用多元回归分析方法,建立了7号煤层NE、NEE和NW向小断层延伸长度的预测模型。实际应用表明,该模型的预测精度较高,比较符合实际情况。A method of multi-variable linear regression analysis by means of the worksheet function of Microsoft Excel is introduced for estimating the parameters of multiple linear regression. Based on the fracture structures re- vealed by mining No.7 coal seam in Zhaoguan mine of Huanghebei coal field, the mathematics module can be founded to predict the small faults by way of using this method. On the basis of discussing the development regu- larities of small faults in No.7 coal seam, we get three mathematics models to predict the small faults in NE, NEE and NW directions respectively. And practical application is given to illuminate the feasibility of the models.
