The 11302 transport joint road of a mine is affected by the poor bearing capacity of the roof rock body,broken and other factors,which makes it difficult to control the surrounding rock.Combined with the field conditions of the perimeter rock deformation control problems faced by the analysis,put forward control strategies,specifically the use of overrun grouting to improve the stability of the roof plate broken rock body,bearing capacity,and then through the anchor mesh rope way to control the deformation of the perimeter rock;on the roof plate grouting parameters and anchor rods and ropes layout parameters,such as the design of the details.After the field application,the anchoring end of anchor rods and cables is stable,and the anchoring force of anchor rods and cables is above 100 kN and 150 kN respectively;the deformation of the surrounding rock in 11302 transport joint lane can be better controlled,and the deformation of top and bottom plates and roadway gangs can be controlled within 59 mm and 68 mm respectively.
