The role of flake ice machine cooling in mines

800 meters below the ground, the temperature rises to about 37 degrees. The operating conditions of the underground mine tunnels are harsh, the temperature is high, toxic and harmful gases, and the air does not circulate. Using flake ice machine to cool down the mine is one of the common methods. It is simple and convenient, and can continue to cool down the mine.

Role in coal mines

Gas and flammable gas are prone to occur in coal mines. Once the temperature of the mine rises, it is easy to explode, and the mine collapses to cause a serious safety accident. The cooling of flake ice can prevent the explosion of flammable gas.

Mine cooling to ensure a comfortable environment for machines and workers

The temperature is high, and the machine is prone to failure. Workers are prone to heatstroke, etc. For every 1°C increase in temperature, mine production efficiency is reduced by 6-8%. In the mining operation surface below -800m, during the three months of summer, the mining operation surface exceeds 30°C, and the coal roadway excavation operation surface temperature reaches as high as 32°C and 33°C. Phenomena such as eczema and heatstroke occur from time to time, seriously affecting the physical and mental health of the workers. Health and safety production, and cause damage to mechanical and electrical equipment, affecting production efficiency and construction safety. People are the foundation of an enterprise, and heatstroke prevention and cooling are an important part of the prevention and control of occupational diseases in coal mines, as well as the basic work of safe production.

More useful cases show that using flake ice to cool down the top of deep mines can achieve the best effect of effectively controlling the internal temperature of mines. The whole system mainly consists of ground ice making system, ice transporting and melting system and underground cooling system Composition, the actual underground cooling system is an open system, that is, the return water flows back to the ice melting pool, and the dust-proof water in the mining area is a small amount of water, which can be connected from the cooling water pipeline to be used for dust prevention and spraying on the working surface. It can effectively reduce the downhole ambient temperature and improve production efficiency. Ensure underground safety operations
