Now, in a coal industry, including mine construction, agrees paragraph 462 /FC/ the use of cables of all purposes /power, monitoring and etc../ with aluminium leaders is forbidden, and in this connection are used more dear also deficient copper cables. At the same time "Rules of the device of the electroinstallations" suppose use of cables with aluminium leaders in explosive zones of some classes. Referring on stated, the problem on realization of researches on study of a capability of replacement of copper wires on aluminium is delivered. Analytical and laboratory researches. Pursuant to the calendar plan the explosive zones and cases are certain, where the replacement of copper conductors on aluminium is possible. Is established, that it is possible in trunks of gas mines, under condition of, the association of wires will be made with application of special external clips. The optimum marks of aluminium have appeared the marks appr opriate GOST 22483-77 and GOST 6132-79. The outcomes of activity on a stage will be used at development 4 stages.
