Rational mode of mine air cooling
Abstract
Currently, at a number of mines in the Stalin‑Makeevsk, Central and other areas of the Donetsk basin, the air temperature in the stoping faces (more than 30 faces) exceeds the limit (26°C) established by the Safety Rules, reaching 28‑30°C in the summer months. 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 and number of air coolers, so that air cooling is quite effective with the least expenditure of cold.
