Essay

The alteration regularities of the rock mass behaviour round the working with various kinds of support setting, including Shatrovay multilink support are being defended. Rational parameters of the steel support with rectilineal elements and dependences for their determination that ensure raising of the working stability are being maintained. It’s going on at the expense of the increasing working kinetic mobility and even redistribution of the support pressure load with alteration of pliability direction along the cross-section of a roadway in the knots of the elements connection. Technical conditions of the working APPK employing are elaborated. The working has taken testing in Zapadno-Donbasskay mine. The permit of Gosnadzorohrantruda for its manufacturing and its employing in the mines of Ukraine was received.
