矿井小构造预测研究

Study on forecast of small structure of mine shaft

为了获得矿井小断层水平延展长度预测研究中相对比较准确的预测公式,基于多元回归分析,在总结实际资料的基础上,以断层的落差、走向、倾角、倾向数据为主要影响因子,研究矿井小断层水平延展长度预测,利用Matlab绘制拟合图,并对其进行多元回归分析,得到矿井小断层水平延展长度预测公式,并对结果进行评价以及DW检验。经检验多元回归分析生成的预测模型具有相对较高的精确度,且在煤矿实际生产中具有相对广阔的应用前景。

In order to have a relative quite accurate prediction formula in the study on the small fault horizontal length,based on the multiple regression analysis method and the summary of the actual data,the fault throw,strike,dip and tendency were applied as the primary influence factors to study the prediction of horizontal extension length of small fault in mine. Normalize the data and draw the fitting graph by using Matlab software and the multiple regression analysis was conducted. A prediction formula of the small fault horizontal length was obtained and the results were evaluated and tested by DW evaluation. Upon examination,prediction model generated with multiple regressions analysis has relatively high accuracy,and has relatively broad application prospects in coal mine production.
