Research on Ventilation Flow Rules of Thermodynamics and Cooling Measures at Jinchuan Mine Ⅱ

摘要

With the increase of the depth of metal mine, geothermy coupled with other factors of various heat sources have more impact, so now heat-harm has became one of the important hazards. In the base of determination of thermal parameters at Jinchuan Mine II we have a detailed analysis on enthalpy, moisture content, relative humidity and air density, and grasp the types and distribution of heat and humidity source. In the Jinchuan Mine II the main heat source is self-compressed hot of ventilation flow, heat dispersal of waste rock, rock and mechanical equipment; the main humidity source is the wet watering humidification, humidification and exploitation of water gushing panel spray dust within humidification. In order to reduce the temperature we propose some control measures to specific heat.
