Statistical Analysis for Frictional Resistance Coefficient of Lining Roadway in Mine

摘要：

In order to accurately obtain the frictional resistance coefficient of lining roadway (without installing belt) , 272 groups of measured data selected from 13 coal mine are statistically analyzed by applying SPSS software and Bootstrap resampling method.At the same time, the data are analyzed by using the cluster method and box line diagram of outliers, tested by using the Kolmogorov — Smirnova and Shapiro — Wilk.The results show that the frictional resistance coefficient resulting from measured data dont follow normal distribution when the extreme value and outliers are rejected from the measured data.By applying the Bootstrap resampling method, the data are statistically computed, and the value range of frictional resistance coefficient is from 0.0046 to 0.0064N.s /m .Applying the statistical results of frictional resistance coefficient to the Lvjiao-tuo Coal Mine, the correlation of hectometer frictional resistance between practical measurement and statistical computation is highly significant.Therefore, the correctness of statistical data is verified.It greatly increases the accuracy and reliability in calculating the frictional resistance coefficient of lining roadway, and it has important guiding significance for the ventilation safety management of mine.
