Essay

Object: the conduction of underground constructions and excavations which are in a zone of the raised mountain pressure. Purpose: a grounding of the parameters of technology erection shotcrete mining excavations of explosive dispersion a cement-sandy mix from easily destroyed packages. Methods of researches: мethods of physical modelling; analytical researches; laboratory and mine researches of dynamics of мovements of a cement-sandy mix, industrial tests, the technical and economic analysis. For the first time is offered the criterion of ranging of substances on their ability sprayed under action of the central explosion. For the first time is received analytical dependence of range of мovements of a cement-sandy mix at the central explosion from its weight, physical and detonation characteristics of a cartridge of explosive. For the first time uniformity of a stream of a cement-sandy mix is characterized by the attitude of power criterion of a charge of explosive to weight of a cement-sandy mix.
