The tutorial provides basic information on the technology of pressure hydraulic transportation of ore, rock that has been used or recommended for underground mining of solid minerals. The scope of application is indicated and a brief outline of the development of this promising type of transport and the lifting of rock mass at a number of mining enterprises of ferrous and non-ferrous metallurgy is given. The basic data of technical hydraulics, which are both methodical and practical in solving some problems of hydraulic transport technology, are briefly described. Physical and mechanical properties of hydraulic mixtures, modes and integral characteristics of pressure movement in pipes are described.
