With the continuous improvement of social level, people gradually pay attention to environmental protection and maintain the ecological balance. However, there are some environmental pollution problems in the development of China's mining industry, which are not only unfavorable to the effective maintenance of the ecological balance, but also unfavorable to the healthy development of the mining industry.展开更多

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.展开更多
