Dissertation work is sent to providing of excavation stability by explosive unloading of rock roof. Laboratory studies have deter-mined the regularities of the unloading rock zones around the mine working. Laws of distribution of stress-straine at unloading was investigated by the method of final elements. Laws of change stability of frame support in development working are investigated by finite-element method under various schemes of unloading depending from changes passive reaction of rocks. Recommendations have been developed to improve the stability of mine workings and transferred to GOAO "Luganskgiproshaht" to be used in preparing new projects and reconstruction of the existing mines. It's were used in drifting of gangway the mine "L.I. Lutugin" of SE "Torezantratsit" and introduced into the mining specialists training educational process.
