Due to the depth of the mines large volumes of chilled water are required at
Jan 11, 2007 · Recently, a number of underground coal mines in the Bowen Basin have installed bulk air conditioning plants to manage thermal stress. Typically, these plants are equipped with four bulk air coolers and one cooling tower (typically 12m in length). These plants are fitted with an automated biocide dosing system to control bacterial growth.
Mining Magazine spoke to CIMCO Refrigeration in Canada, which has been involved in deepmining projects for over 50 years. The majority of this work has been in ground freezing for both uranium and potash mines, but, more recently, this has included chilling systems for cooling ventilation air to minimize the number of rest periods required during
Traditional central air conditioning is not always the best fit for every home. If you have an older home, installing wholehome air conditioning may not be possible due to lack of space for ductwork. Fortunately, there''s a popular, flexible solution: ductless heating and cooling units, known as ductless mini split air
It was also necessary to install a surface bulk aircooling facility, which cools 400 kg/s of ventilation air going to the underground workings. Primary cooling is to the surface bulk air cooler. The cooling duty of a surface bulk air cooler is heavily dependent on the ambient wetbulb temperature.
