Abstract: under the condition of the soldis backll cal mining the deformation of the surrounding rock in the upper overburden roadiway was afcted by several factors. Based the geological conditons of No.3644 coal mining face in Yangzhuang Mline,the ABAQUS was applied to estabih the surounding rock deformation anayss model of the upper overourden roadvay with the solis backll mining. The paper stressed the study on the three factors of the compact rate,the horzontal distance between the open- off cut and upper overburden roadway and the lengh of the backl mining face affected tothe surounding rock defomation ofthe mine rcadiway certain,three indexes of th total subsidence value of the foo,the convegence between the roof and foor and the convergence between the two sidewels were presetted.The surrounding rock deformation indewes of the three mine roadways were decrease in lnear with the repleton rate increased,with thelength of the bac.l. roring face and the horzontalditance bewee the open- of cut and upper level radway inreased with " a semi parabola type" increased law;a multiple noliear regression method was applied t fit the function relationship between the three indexes of th foortatal subsidence value.the roof and foor convergence and twvo side al cnvergence and the thvee infuence factors. The project practices showed that the total subsidence fiting value of the foorat No.11 mornitoring and measuring station "as 157 mm and the actual measured subsidence value was 163 mm.There was 6 m diference between the two vaues and the simulationrl aility was indidually pproved.
