L1, L3 hor..550 of m. of mine "Diamond". Development of the technical decisions ensuring maintenance of developments in an operational condition. Analytical and experimental researches. The analysis of mine-geological and mine technical conditions of construction of mountain developments is executed and the major factors influencing to their stability are established. The methodical approaches to an estimation of geomechanical influences on developments during term of their service are certain. The advantages of strenghtening rock mass by anchors, having coupling with walls of a chink on all to its length are shown. The developed technical decisions and the documentation is transferred to institute "Dneprogidromine" and will be used with updating the project of opening and preparation of mountains. 830 m. of mine "Diamond" CHC "Dobropolyecoal".
