High strength steel tube confined concrete supports (STCCS) are adopted with the main steel tube of high-strength STCCS and Φ159mm × 8mm steel seamless pipe, with the internal filled core concrete of C40 strength standard, and with the ultimate bearing capacity of STCCS of 1894.3kN, according to a theoretical calculation. With the FLAC^3D numerical simulation and the in-situ monitoring, the influence of 18 coal face's recovery on the surface displacement and the stress state of -225 roadway sounding rock is analyzed. The results show that the mine strata pressure behavior is significant in the scope of 30m to the working face during the mine dynamic pressure of the 18 coal face's recovery, the maximum vertical stress is 27.4 to 42.9MPa, and the stress concentration factor is 2.27 to 3.57. The surface displacement of -225 roadway sounding rock is less than 20mm when it is supported by STCCS, which meets the stability requirements of the roadway surrounding rock., authors=LI Xuebin, GAO
