Integrated use of mine openings in cryolithic zone

The results of theoretical and practical research on basis of modular type underground facilities design and construction are under analysis. Some mine openings of underground facilities were suggested to use as heat-exchange modules in order to reduce the energy costs for establishment of the thermal condition in the main mine openings. The worn mine openings can be used as heat-exchange modules for producing mines. It was discovered that the inclusion of additional openings in mine ventilation system do not cause the additional costs because the result of costs reduction for the mine air aeration is more efficient than the costs increasing for conditioning of additional openings. Moreover, the heat-exchange module openings can be used as protective shelters for workers and residents in case of natural or man-caused emergency. It is suggested to spread the experience practice of underground facilities design and construction in Sakha Republic (Yakutia) over the whole area of cryolithic zone. © Metallurgical and Mining Industry, 2015.
