product description

Mine cooling equipment

With the increasing depth of modern mining excavation, the occupational hazards of mines are becoming higher and higher. One of the main factors is the rise in mine temperature, which is mainly caused by geothermal energy in mines, in addition to equipment heating. This is the main reason for the high temperature in deep wells. The deeper it is from the surface, the higher the temperature of the rock. The increase in rock temperature (geothermal gradient or geothermal heating rate) for every 100 meters of vertical depth below the constant temperature zone varies in different regions. For example, the Fushun mining area has a temperature increase of about 3.3 ℃, while the Shizuizi copper mining area in Jilin has a temperature increase of about 2 ℃. The rock temperature at a depth of 1000-1200m in the Ruhr coalfield of Federal Germany has reached 50-60 ℃. A deep well of about 1000m, due to the heat exchange between the rock wall and the air, the heat emitted by the strata can account for 40-50% of the total heat source of the mine. When groundwater is connected to deep-seated heat sources through faults and fractures, underground hot water activity can form local geothermal anomaly zones.

The Worsley mine cooling and refrigeration unit is designed professionally based on the operational characteristics of the mine, with a focus on high safety and reliability while meeting the functional requirements of the system. The main products currently available are: A、 Mobile air cooling equipment is commonly used for cooling in local locations such as mining workfaces; B、 Fixed air cooling equipment is a type of refrigeration equipment that uses a water or air system to deliver cooling to the required area. It is generally used in larger workplaces. The powerful high safety and reliable design application of this series of products is an effective guarantee for the safety of deep mining operations.

◆System form

Mobile series local cooling unit for mines

In order to better and effectively mine underground mineral resources such as gold mines, the mining depth is constantly increasing. As the mining depth exceeds the constant temperature layer, for every 100 meters increase, the temperature of the mining face will rise by 2.5 ℃ or even higher. When the mine reaches a certain depth, a high-temperature mine is formed, which will cause great physical harm to the underground mining personnel. Our company's technical personnel have successfully developed and designed the KLS series of mobile local cooling units for mines through extensive investigation and research, with the help of domestic mining safety production experts. The cooling capacity ranges from 45 to 450 kilowatts, making it convenient for various types of mining to choose from. This series of products features small size, easy mobility, dust prevention, and high temperature resistance.

Fixed series local cooling unit for mines

There are three layout options for this series of products: (a) both the refrigeration and cooling systems are located on the ground, with the main cooling air intake. Its construction, maintenance, and treatment of cooling water (used to cool the refrigerant in the condenser) are relatively convenient, but the cold air absorbs heat during transportation underground, reducing the cooling effect. (b) The refrigeration system is located on the ground, and the cooling system is located underground. It requires a large investment, but the cooling water is easy to treat and has good cooling effect. High quality insulation materials can be used to prevent cold water from absorbing heat during transportation. (c) The refrigeration and cooling systems are both located underground, which requires a proper solution to the problem of circulating cooling water. This series of products is widely used for air conditioning in large underground working environments. Cooling range: 177~3340kW; This series of units has the characteristics of easy operation, stable operation, safety and reliability, and convenient maintenance.
