Problems solved by technology

[0007] ③ Ammonia flow separator, compressor, condenser, etc. are still used for refrigeration, and the system is more complicated
[0008] ④ Multiple systems exchange cooling capacity, reducing efficiency
[0009] Due to the high temperature of the original rock, the water temperature in the low-temperature water tank in the mining area rises significantly, especially when the water volume is small or intermittent, the water temperature may be consistent with the original rock temperature, and the cooling capacity is huge.

Embodiment Construction

[0028] Accompanying drawing is the specific embodiment of the present invention. Such as figure 1 As shown, this kind of mine cooling system includes an air intake shaft 1 below the ground 9, a cooling air intake shaft 3 is excavated next to the air intake shaft 1, and several cooling air intake shafts are dug horizontally after the cooling air intake shaft 3 is connected to the stratum constant temperature zone 7. Lane 4 communicates with air inlet shaft 1, in order to enhance the cooling effect, a container for adorning ice or spray water pipe 8 can also be added in cooling lane 4; figure 2 and image 3 As shown, the cooling lane 4 can be designed in a wavy or sawtooth shape, so that the hot air can absorb more cold air in the cooling lane 4, and the cooling effect is better; an opening and closing door is installed at the point where the cooling lane 4 communicates with the air inlet shaft 1 6. A fan 2 is provided at the entrance of the cooling air intake shaft 3, and a ...

Abstract

The invention relates to a cooling system, in particular to a mine cooling system which comprises a downcast shaft. The mine cooling system is characterized in that a cooling downcast shaft is further included, after the cooling downcast shaft reaches the stratum constant temperature zone, the cooling downcast shaft is communicated with the downcast shaft through a plurality of horizontal cooling lanes, a fan blower is arranged at the inlet of the cooling downcast shaft, and a cover plate is arranged at the opening of the downcast shaft. A container for containing ice or a spray pipe is arranged in each cooling lane, an opening and closing door is arranged in each cooling lane, and the opening and closing door is located at one end, close to the downcast shaft, of each cooling lane. The mine cooling system has the advantages of being simple in structure, low in energy consumption, good in cooling effect, and high in cooling efficiency.

Description

(1) Technical field [0001] The invention relates to a cooling system, in particular to a mine cooling system. (2) Background technology [0002] With the increase of coal mine mining depth, the temperature of underground mining sites gradually rises, and mine heat damage causes great safety hazards and even affects normal production. Article 102 of the "Coal Mine Safety Regulations" "The air temperature of the mining face of the production mine shall not exceed 26°C, and the air temperature of the electromechanical equipment chamber shall not exceed 30°C; When the air temperature of the mining face exceeds 30°C and the air temperature of the electromechanical equipment chamber exceeds 34°C, the operation must be stopped.” Gold mines, iron mines, etc. have similar regulations. [0003] At present, there are roughly two types of heat damage in mines. One is high temperature throughout the year, and the other is high temperature only in summer, and the underground temperat...
