Rational mode of mine air cooling
Abstract
Currently, at a number of mines in Stalin-Makeevsk, Central and other areas of the Donetsk basin air temperature in the cleaning faces (more than 30 faces) exceeds the limit (26°) established by the Safety Rules, reaching in the summer months 28-30° The most radical means of combating high temperatures, which at a certain depth of mining operations become inevitable, is artificial cooling of mine air. When choosing a cooling system, it is important not only to find a cheap and technically convenient way of obtaining cold, but also to correctly address the issue of the location of air coolers and their number, so that air cooling was quite effective with the least amount of cold.
