| 2 | Study and practice of the controlling technique on heat-harm during the tunneling in Zhaolou mine显示文摘This paper proposes the cooling system type and cooling equipment type which are deep mine with high temperature during the construction,and presents auxiliary cooling measures making up duct temperature rise since compression and heat transfer temperature rise. The cooling system designed against Zhaolou mine's ground temperature and weather conditions,with its sprinkler room handling an average temperature difference up to 19.5~23.8 ℃,and the average enthalpy difference could reach 48.4~60.7 kJ/kg. At the same time,it gets a series of basic data used for mine construction during the cooling system design and equipment selection according to the measured results; using the analysis software Matlab,it obtains the change relations between the temperature of sprinkler room and fan export supply air temperature,wind casing temperature rise and fan export supply air temperature,working face temperature and supply air temperature,used for the mine cooling which has the similar conditions. | Liu Heqing Hao Xiaoli Wang Yongjie Dai Huadong Lin Qiguo | 2008 | Engineering Sciences2008，6，4： | 0 |
