Abstract: The article describes the experience of preserving a mine working with a hard-to-control roof, describes the geological and mechanical processes occurring in the strata of extraction pillar 555, as well as the results of monitoring the convergence before and after the directional hydraulic fracturing and displacement of the roof strata in conveyor roadway 555. A number of studies addressing the actual geological conditions of the roadway enclosing rock are presented. The analysis of the effectiveness of measures that allowed to solve the problem of maintaining conveyor drift 555 for the entire service life in an accident-free condition was carried out.

Key words: preservation and maintenance of mine workings difficult to manage roof abutment zone pillar displacement convergence
