ABSTRACT
Regulation of mine thermal regime is extremely important to assure the stability of the mine openings. This paper examines engineering control of mine thermal regime by thermosyphons placed on the surface of the mine. The results indicate that with the thermosyphons installed over the airway roof, a cold area is developed at the top of the roof. The cold area, in some degree, resembles a dome covering over the airway roof. The development and maintenance of this cold dome must be carefully considered in frozen ground when planning the support system of an underground mine opening near the surface.
