Abstract: Based on the backdrop of filling retaining roadway with super-high water material in the coalmine in Shanxi Province, a synergistic control technology of cable-stayed anchor cable-filling body-U steel is proposed combining with the characteristics of surrounding rock movement of in-situ retained roadway. The key of this technology is to make full use of the suspension effect of stayed anchor cable on roof rock stratum, and to form a stable cantilever beam structure with solid coal side as the fulcrum of overburden rock with the cutting of U steel and single pillar. Besides, the super-high water filling body with certain compressibility yields moderately at the initial stage, adapts to roof deformation, and bears load at the later stage, which limits the lower strata to break and keeps the roadway stable for a long time. In the initial stage of field application, the observation of rock pressure shows that the retained roadway has obvious lagging deformation characteristics, and the roof is stable. The main deformation of the retained roadway is floor heave, which is the key point of surrounding rock control of the retained roadway. Combining with the observation results, the reasons are analyzed and the supporting scheme is adjusted. By measures of dense pillar roof cutting, pre-support and bottom bolting, the deformation of roadway is obviously reduced, and the requirement of secondary mining can be satisfied without repairing or simply undercover.
