The research on calculating formula of coefficient of frictional resistance of bolting and shotcreting roadways
锚喷巷道通风阻力系数的计算式研究
According to the the regression analysis on the bloting and shotcreting roadways of henan pingmei group , the regression equation on the degree that absolute grade and area of roadway influence coefficient of frictional resistance is built in the paper . the notable character test of the regression equation is completed . at last , the degree that absolute grade and area of roadway influence coefficient of frictional resistance is discussed and summed up . the practical and guiding sense in choosing coefficient of frictional resistance of congeneric roadways is given in the paper
通过对平煤集团大量的锚喷巷道的回归分析，建立了巷道壁面绝对粗糙度和巷道断面积对摩擦阻力系数影响程度的回归方程，并对回归方程作了显著性检验，最后对巷道粗糙程度和断面积对锚喷巷道摩擦阻力系数的影响程度进行了讨论和总结，对同类巷道摩擦阻力系数的选取具有实践指导意义。
