With the development of modern mining mining depth is more and more deep, more and more high occupation hazards of mine, one of the main factors is the increase of mine temperature, the temperature of mine main factors besides equipment fever, mainly is mine geothermal, this is mainly due to the temperature of the deep. The deeper the surface, the higher the rock temperature. With drooping from the constant temperature increase deep rock temperature increment 100m (temperature gradient and geothermal warming rate) in each district is different, such as the Fushun mining area is about 3.3 degrees Celsius, Jilin Shi Ju Zi copper area is about 2 degrees celsius. The coal seam temperature of the Ruhr coal field in the Federal Republic of Germany ranges from 1000 to 1200m, and the temperature has reached 50~60 degrees. Because of the heat exchange between the rock wall and the air, the heat generated by the stratum can account for 40 ~ 50% of the total heat source of the deep mine around 1000m. When the groundwater is connected by the fault and fissure with the deep heat source of the stratum, the local geothermal anomaly can be formed by the underground hot water activity.
Worsley coal mine cooling refrigeration unit aims at the operation characteristics of the mine, through professional design, on the basis of meeting the functional requirements of the system, with high safety and reliability as the leading ideology. Our main products are: A, mobile cooling air cooling equipment commonly used in mining face of local place; B, fixed type air cooling equipment fixed by refrigeration equipment, water system or system will wind cooling capacity to the needs of the region, the working face is generally used in high places. The powerful safety and reliability design of this series of products is an effective guarantee for the safety of deep mining operations. The characteristics of this series of products mainly include the following characteristics:
The product specifications: in the product application, Worsley developed a number of product specifications based on different applications, to meet the needs of different applications.

The system form
Mine mobile series local cooling unit
In order to fully and effectively mining underground gold and other mineral resources, mining depth increasing, with more than constant temperature layer mining depth, each additional 100 meters, the temperature of working face will rise of 2.5 degrees Celsius or higher temperature, when the mine reaches a certain depth on the formation of the high temperature mine, to mine mining personnel bring great bodily harm. Our company technical personnel through a large number of investigation and research, and in the domestic mining safety production expert with the help of the successful development of the design of KLS series of mine mobile local cooling unit. The range of cooling capacity is 45~450 kW, which is convenient for various types of mining. This series of products have the characteristics of small size, easy moving, dustproof and high temperature resistance.
Mine fixed type series local cooling unit
The series comes in three different ways: (a) cooling and cooling systems are located on the ground, cooling the total air intake. Its construction, maintenance and cooling water (used to cool the refrigerant in the condenser) are more convenient to handle, but the cold air will absorb heat and reduce the cooling effect. (b) the refrigeration system is on the ground and the cooling system is in the well. The investment is large, but the cooling water is easy to handle and the cooling effect is good. High quality insulation materials can be used to prevent cold water from absorbing heat during the transportation process. (c) both refrigeration and cooling systems are located underground, which requires proper treatment of cooling water cycles. This series of products are widely used in the air conditioning of the working environment in large mines. Refrigeration range: 177~3340kW; this series of units has the advantages of simple operation, stable operation, safe and reliable, convenient maintenance and so on
