With the development of Kuzbass in Russia, the foreign electric head- lamps appeared. In the workshops of the Prokopyevsk mine, the first domestic samples were fabricated, the production of which was organized at the Prokopyevsk mine automation plant. For many years the plant produced headlamps for the whole of the USSR, gradually improving the design and parameters. The growth of the requirements to ensuring safety has made necessary the creation of the design that will combine a headlamp and a methane alarm, which significantly reduced injuries in case of accidents.
Transition to the standards of the International Electrotechnical Commission, new construction materials and energy-intensive accumulator batteries made it possible to create the design of the lamps of smaller dimensions and weight with a large energy margin. When implementing multifunctional safety systems in mines, the lamps due to their connection with the miner and the availability of power margin have become the carriers of blocks of these various systems. This does not facilitate the reliability of the lamp itself, especially if additional devices are connected directly to its electrical circuits.
Currently the lamp, in addition to the main function and measurement of methane, carries the elements of the system of positioning, warning, search in rock bursts, etc., moreover, all that is made with different structures and interfaces. The developers are not rushing to unification trying to enclose the market share. There was a proposal to introduce other elements of air-gas control systems into the lamp. The consequences of this decision and the proposed ways of how to resolve the situation are considered in the article.
