Abstract: In order to solve the problem that the roadway in the 9102 working face of Heng sheng coal industry is affected by the overburden movement in Goaf, the tunnel deformation is rapid, the displacement quantity is large, and the ore pressure appears violently. Through the field surrounding rock deformation observation, drilling peep, Rayleigh wave detection and other means to the Heng Sheng Coal industry 9102 face Machine Lane monitoring. Through the field surrounding rock deformation observation, drilling peep, Rayleigh wave detection and other means to the Heng Sheng Coal industry 9102 face Machine Lane monitoring. Rayleigh wave detection roof indicates that the abnormal area of rock mass structure is distributed in 1m~1.5m and 2m~5m, the damage of roof drilling peep image is seriously damaged near 1.5m and 3m, the collapse hole appears at 4m, the roof off-layer instrument appears off layer in 2m~3m and 3m~5m. According to the monitoring results, the supporting parameters are optimized and tested, and the results show that: the deformation of the surrounding rock of 9102 Machine Lane is small, the displacement of the top bottom plate is 77mm when the measuring point is 140m, the displacement amount of the two pairs is 98mm, and the effect of roadway support is obvious.
