Abstract: The roadway driven along goaf and heading for adjacent advancing coal face was in full procedure influenced by the dynamic pressure occurred by the lateral main roof broken，turned and stabilized of the upper sectional coal face，the surrounding rock would occur large deformation and difficult to maintain．This paper researched the surrounding rock deformation rule and control technique by theoretical analysis，numerical calculation and field test. The result shows that this roadway would occur asymmetrical deformation，small coal pillar and roof deformed greatly，improve support strength of small coal pillar and roof was the key to remain the roadway stable．According to the research，the better supporting technology is shown as follows: 1）Reasonably determine the width of small coal pillar，kept roadway in stress decreasing zone；2）High strength and large elongation anchor controlled deformation of surrounding rock；3）Reinforced support of the small coal pillar and roof to improve the carrying capacity of key parts．According to the engineering application in Qipanjing Mine，the supporting technology effectively controlled the deformation of surrounding rock of roadway，and achieved good results．
