小断层延伸长度定量化预测在王家塔井田的应用

Application of quantitative prediction of small fault extension length in Wangjiata Mine Field

为准确掌握小断层的延伸规律,降低小断层对矿井采掘活动的影响,以王家塔井田3-1煤层在采掘活动中揭露的小断层资料为依据,选取断层走向延展长度、断层落差和断层倾角3个因素,采用多元线性回归的方法,分别建立NE向和NW向小断层延伸长度的回归预测模型。实际应用表明,利用该回归模型可以为王家塔矿井内的小断层延伸长度提供可靠的预测。

In order to accurately master the elongation law of small fault and to reduce the impact of small fault on mining and mining activities in mines,based on the small fault data revealed in the mining activities of No.3-1 coal seam in Wangjiata,adopted multiple linear regression methed through analyzing the extended length,fault throw and angle of three factors of fault,and the fault extended length regression models were built at NE and NW directions.It was shown that this prediction model can provide reliable prediction for the length of small faults in Wangjiata Mine Field.
