Currently, the industrial development of the ocean is actively developing and one of the main directions of work on the study of its resources is the extraction of minerals. For the extraction of minerals on the shelf a complex of machines and apparatuses has been created, which includes dredgers, underwater bulldozers of "Komatsu" type, robots "Nihon" and "Komatsu", RUM apparatus, "Hitachi" system, various walking rigs developed and tested in the Soviet Union.
Extraction of the bulk of coal, carried out by underground method on horizontal and declining seams, is carried out by narrow-capture harvesters installed on mechanized complexes. The efficiency and reliability of the mechanized longwall face depends to a great extent on the quality of manufacture or overhaul of the mining combine ...
Working in a quarry is subject to the influence of meteorological conditions characteristic of the area and harmful impurities emitted into the atmosphere of the quarry during various production processes. Precipitation, changes in temperature and wind speed at the surface entail changes in the corresponding parameters at workplaces. The most unfavorable of all natural factors is temperature, since most of the quarries of the USSR is located in the zone of sharply continental climate with average winter temperatures of minus 15-20 ° and summer temperatures of +20-30°.
