special-destination lubricants. SUBSTANCE: invention relates to lubricants that can be applied to prevent dust formation on temporary motor car roads in open cast mines as well as to prevent sticking, freezing-on, and freezing together of wet rocks on walls of mine-transportation equipment, for instance to protect surfaces of vehicles from freezing-on and blowing-out of loose materials, e.g. coal, peat, and the like. Lubricant contains 1.0 to 20.0% of heavy petroleum residue and 80,0 to 99.0% of furnace oil (pyrolysis tar rectification bottoms) or absorbent, in particular synthetic isoprene rubber monomer production waste. EFFECT: improved performance characteristics, lowered freezing temperature, and extended resource of inexpensive raw materials. 2 cl, 1 dwg, 3 tbl, 2 ex
