Problems solved by technology

Although these two technologies can produce cooling effect underground, their biggest drawback is that the amount of water gushing underground will double, causing great difficulties for underground drainage of mines, and sometimes it cannot be discharged. If the drainage pump is added , Replacement of thicker drainage pipes and other facilities will cause huge investment waste to the mine, and even the loss outweighs the gain

Embodiment 1

[0021] Embodiment 1: as figure 1 As shown, in the downhole comprehensive refrigeration method of the present invention, the water in the pool 2 is transported as a refrigerant to the refrigerator 3 through the water pump 1, and the refrigerator 3 cools down the water in the refrigeration compartment of the refrigerator 3 through the water in the pool 2 Make cold water, the cold water generated by the outlet of the refrigerator 3 is transported by the high-pressure water pump 4 through the water supply pipe to one end of the coil fan 5 in the mine, and the other end of the coil fan 5 is connected to the refrigerator 3 through the return pipe, and the coil fan 5. Through the cold water entering it, the cold wind is blown out.

Embodiment 2

[0022] Embodiment 2: On the basis of the structure described in Embodiment 1, the water in the pool 2 is mine groundwater located on the surface of the mining area. According to the water quantity and water temperature of the water in the pool 2, the mine groundwater is constantly added to the pool to supplement the water in the pool. The water quantity and reduce the temperature of the water in the pond, the water delivery pipeline and the return water pipeline comprise the water delivery main pipeline 6 and the water delivery branch pipeline 7 and the return water main pipeline 8 and the backwater branch pipeline 9, and there are stopes, chambers and independent mines under the mine The head excavation working face, the stope, the chamber and the single head excavation working face are all equipped with a coil fan 5, and one end of the main water supply pipe 6 and the main return water pipe 8 is connected to the refrigerator 3, and the other end is respectively connected to th...

Embodiment 3

[0023] Embodiment 3: On the basis of the structure described in Embodiment 2, a local ventilator 14 is arranged at the working face of the single-head excavation, and the cold air blown out by the coil fan 5 is sent to the working face, and the coil fan 5 and the local ventilator 14 They are explosion-proof coil fans and explosion-proof local fans with MA safety signs respectively. The refrigerator 3 is provided with a water return port, which is connected to the pool 2 through the return pipe 13, and the groundwater used by the refrigerator 3 is recycled to the pool. 2 for reuse.

Abstract

The invention provides an underground comprehensive refrigerating method and belongs to the field of underground refrigerating ventilation equipment. According to the method, water in a water tank serves as a refrigerant to be conveyed to a refrigerating machine through a water pump, water in a refrigerating bin in the refrigerating machine is cooled to form cold water through the water in the water tank by the refrigerating machine, the cold water generated at the water outlet of the refrigerating machine is conveyed to one end of a coil pipe fan in a mine shaft through a water conveying pipeline by a high-pressure water pump, the other end of the coil pipe fan is connected to the refrigerating machine through a water return pipeline, and cold air is blown out by the coil pipe fan through the cold water entering the coil pipe fan. Therefore, the refrigerating effect is good, the underground water inflow quantity cannot be increased, and the refrigerating cost can be satisfactorily controlled.

Description

technical field [0001] The invention provides an underground comprehensive refrigeration method, which belongs to the field of underground refrigeration and ventilation equipment. Background technique [0002] In recent years, in order to meet the stable annual output of underground mines in my country, the mining depth has been deepened year by year. With the increase of mine mining depth, the temperature of surrounding rock in underground roadways has increased, resulting in underground mining, excavation working faces and various chambers. The ambient temperature is getting higher and higher, especially in various mining fields and tunneling working faces in the underground. The general temperature is around 35°C to 45°C. Work is also covered with sweat. Generally, if you can’t last for two or three hours, you have to change places or people. The work efficiency is very low, which is very detrimental to the physical and mental health of underground workers. There is an urge...
