METHOD TO CONSTRUCT, EQUIP AND OPERATE STATIONARY WAITING CHAMBERS IN DEEP MINES OF NORTH

摘要

FIELD: mining.;SUBSTANCE: method to construct, equip and operate stationary waiting chambers in deep mines of the North includes driving, strengthening and equipping of sealed access and chamber-like formations in the area of pit bottom. Waiting chamber has two sections, on inner surface of which a heat insulation layer of light concrete is applied by shooting method, having multifunctional purpose. Waiting chambers are operated in two modes: at positive temperature mode in pit bottom, miners are arranged in both sections, and at negative temperature - transferred to a sealed heat insulated section, heated with metabolic heat, at the same time coefficient of heat conductivity of light concrete shall make 0.6-0.7 W/mK, and sorption capacity is 600 l/m².;EFFECT: efficient and highly effective method of construction and equipment of waiting chambers, safety of miners arrangement under conditions of emergency situations, no necessity to change miners clothes for warm ones in winter period.;1 dwg
