以翟镇煤矿实测小断层数据为研究对象,利用散点图法和灰色关联法对断层要素间的相关性进行分析,发现断层延展长度与倾向、走向、倾角、落差间非线性关系。基于支持向量机建立小断层延展长度非线性预测模型。通过对比翟镇、良庄煤矿小断层实测数据与预测数据,发现预测模型预测准确度高,还能进行相似地质条件下预测。 Based on the measured data of small faults in Zhai coal mine, the correlation between fault elements is analyzed by scatter diagram method and gray correlation method, and the nonlinear relationship between fault extension length and dip, strike, dip and drop is found out. Establishing nonlinear prediction model of small fault extension length based on support vector machine. By comparing the measured data and prediction data of small faults in Zhai and Liangzhuang coal mines, it is found that the prediction model has high prediction accuracy and can be predicted under similar geological conditions.
