Sklepovych K. The Substantiation of parameters of the rocks strengthening technology on the concluding fields of drifts

The thesis is dedicated to the substantiation of parameters of the rocks strengthening technology by means of forcing of fastening compounds on the concluding fields of drifts. The analysis of the technical literature and the experiment of rocks strengthening on the Donbass mines showed, that the main reason for small volume of strengthening use is the high cost of these works, which is determined by the technology parameters and that's why the substantiation of parameters on the geomechanical principles is necessary.The properties of rock massif on the concluding fields of drifts and in frond of the purifying faces were studied: riftability, permeability, emptiness and deformations. Their dependence on mining - geological and mining - technical factors is established. The pay - scheme for determination of the outline of the filtration flow of the compound injection by the forcing through the bore-hole is worked out and formula for the determination of consumption of the fastening compounds on bore-hole is suggested. According to the scheme consumption is three times less than it is set in the normative documents. The fastening compounds on the basis of carbamid tar with prolonged term of becoming firm are worked out and their technological properties are studied. As a result of mathematical designing, laboratory and mine studies the parame-ters of rocks strengthening technology on the concluding field of drifts are motivated and the methods of parameters determination, which are introduced in mine by name of the XІXth Congress of CPSU, ME "Luganskugol'", are worked out. The main subject of the work is reflected in nine articles and reports on the international and home scientific - technical conferences and in one patent.
