‌The role of block ice machines in cooling down mines is mainly reflected in the following aspects‌:

1.‌Reducing the temperature of mines‌: Block ice machines can effectively reduce the temperature inside mines by making ice and releasing cold air. Excessive temperature inside mines can lead to problems such as machine failure and heat stroke among workers, and the low temperature environment provided by block ice machines can significantly improve this problem‌.

2.‌Improve production efficiency‌: For every 1°C increase in mine temperature, production efficiency will decrease by 6-8%. By using block ice machines for cooling, the production efficiency of mines can be improved and equipment failures and downtime caused by high temperatures can be reduced‌.

3.‌Protect workers' health‌: In high temperature environments, workers are prone to heat stroke, which affects their physical and mental health and safe production. The use of block ice machines can provide a more comfortable working environment and reduce the occurrence of heat stroke and other health problems among workers‌.

4.‌Prevent safety accidents‌: Excessive temperature in mines may cause explosions of flammable gases such as gas, leading to serious safety accidents. The use of block ice machines can effectively avoid this situation and ensure the safety of miners

The application of ice slurry delivery system in mine cooling is mainly reflected in its efficient cooling capacity and economy

The ice slurry cooling system builds an ice-making station on the ground, produces flake ice, and sends ice slurry to the ice melting pool at the bottom of the well through the ice delivery insulation pipeline. The melted low-temperature water is transported to the working face through the insulation pipeline, and the heat is dissipated in various ways to reduce the temperature of the working face. Specific application methods include:


Air cooler heat dissipation: heat exchange is carried out through the air cooler to cool the incoming air flow. The flowing low-temperature air flow takes away part of the heat and reduces the temperature of the working face.‌


Spraying device‌: a spraying device is installed on the upper part of the working face to spray the low-temperature cold water of the cooling system to cool the gas and rock wall of the working face, further reducing the temperature of the working face.

‌Water for mechanical cooling‌: use the low-temperature water of the cooling system to cool the machinery on the working face and reduce the heat dissipation of the machinery.

Characteristics of ice slurry and its advantages in mine cooling
Ice slurry refers to a solid-liquid two-phase solution containing a large number of suspended ice crystal particles, which has the following characteristics:
‌Strong cold transport capacity‌: Ice slurry can efficiently transport cold and is suitable for long-distance cooling needs.
‌Small water pump load‌: Compared with traditional water cooling systems, ice slurry has good fluidity and reduces the load on the water pump.
‌Obvious economic benefits‌: The ice slurry cooling system can not only effectively cool down, but also reduce operating costs through recycling, which has significant economic benefits
