Abstract:Based on the gob-side entry retaining reparation engineering of first coal mining face in Zhuji mine around 900 m underground,deformation,stress and structure state of roadway surrounding rock before reparation were analyzed by field measurement and theoretical method;the conception of“critical structure between instability and stability”of gob-side entry retaining reparation was proposed;reasonable repairing time and construction process were determined;initiative-passive collaborative supporting system was concluded. Research result was applied to the gob-side entry retaining reparation engineering in Zhuji mine successfully. The results of ground pressure monitoring show that the deformation of this repaired roadway is controlled effectively;and all indices satisfy the requirements of next mining face.
