The research on calculating formula of coefficient of frictional resistance of bolting and shotcreting roadways 錨噴巷道通風(fēng)阻力系數(shù)的計(jì)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 通過(guò)對(duì)平煤集團(tuán)大量的錨噴巷道的回歸分析,建立了巷道壁面絕對(duì)粗糙度和巷道斷面積對(duì)摩擦阻力系數(shù)影響程度的回歸方程,并對(duì)回歸方程作了顯著性檢驗(yàn),最后對(duì)巷道粗糙程度和斷面積對(duì)錨噴巷道摩擦阻力系數(shù)的影響程度進(jìn)行了討論和總結(jié),對(duì)同類(lèi)巷道摩擦阻力系數(shù)的選取具有實(shí)踐指導(dǎo)意義。
