Engineering Physics Annotation << Back ENGINEERING AND PHYSICAL BASICS OF USING THE THERMAL RESOURCE PERMAFROST ZONE IN UNDERGROUND MINING OF GOLD DEPOSITS Yu.P. GALCHENKO The main distinguishing feature of the permafrost zone - low average annual air temperature and its conjugate negative temperature rocks located below the zone of summer thawing. The temperature of these rocks in combination with average winter temperature is a regional resource, opening new possibilities for the solution of a number of technological and environmental challenges. Among the latter only important is the problem of accumulation at the surface of dispersed solids mining and processing industry, which can be returned to the underground space in recovery therein array permafrost from frozen on the surface of the briquettes produced in the final stage of enrichment by applying press filters in combination with a roller press. Grounded and built the concept of geotechnology develop closed-loop solid circulation and the method of formation of the sequence and duration of mining operations cycle stages, depending on the structure and value of the local temperature of the resource in the region at various stages of the field portion of the development process. Keywords: permafrost, geo-ecology, temperature, rock temperature, cryogenic technology resource lodes, development, closed-loop, solid waste production, geotechnology, an array recovery, permafrost.
