Method for cooling mine working face by using mine water

Abstract

The invention discloses a method for cooling a mine working face by using mine water. An adopted cooling device comprises a reservoir, a valve, a driving water pipe, a liquid-driven convector and a conveying pipe, wherein the cooling device is arranged below a water-containing layer, the cooling device flows from a high position to a low position by using the gravity action of low-temperature water in the water-containing layer, furthermore, the liquid flowing force is achieved, one part of the low-temperature water enters the liquid-driven convector to serve as a cold source, the other part of the low-temperature water reaches a liquid-driven injection port of the liquid-driven convector through a driving water pipe, the part of the low-temperature water enters the liquid-driven convector through the liquid-driven injection port to drive the liquid-driven convector, furthermore, the cold source in the liquid-driven convector exchanges heat with the air, and the cooled air enters the conveying pipe through an exhaust port and finally flows into a high-temperature working surface area to cool the high-temperature working surface area. According to the method, the mine water is used as a cold source and a power source under the action of gravity, so that the working face of the mine can be cooled without an additional power source.

Description

technical field [0001] The invention relates to a method for cooling down a well with a single power source, in particular to a method for using mine water to cool down a mine working face. Background technique [0002] At present, the cooling of areas such as working faces in underground mines generally adopts air-conditioning equipment similar to that on the mine, but in fact, not every mine has a cooling demand with a large temperature difference, and not every area in the mine needs systematic and significant cooling. , if all air-conditioning equipment is used, the cost is high, and the heat generated cannot be discharged from the shaft, which is likely to cause the temperature in the non-cooling area to rise. For some local temperatures that are not very high, but still have a physical and mental impact on personnel high temperature area. [0003] In addition, in the mine cooling industry, a variety of existing technologies or devices already exist for cooling treatme...

[0002] At present, the cooling of areas such as working faces in underground mines generally adopts air-conditioning equipment similar to that on the mine, but in fact, not every mine has a cooling demand with a large temperature difference, and not every area in the mine needs systematic and significant cooling. , if all air-conditioning equipment is used, the cost is high, and the heat generated cannot be discharged from the shaft, which is likely to cause the temperature in the non-cooling area to rise. For some local temperatures that are not very high, but still have a physical and mental impact on personnel high temperature area

[0003] In addition, in the mine cooling industry, a variety of existing technologies or devices already exist for cooling treatment, but basically all of them require additional power such as electricity, and there are also some open invention patents in the aspect of using mine aquifer water sources to cool down, such as applying for No.: 201811213154.3, titled: A self-pressurized cooling and dust removal system using mine aquifers; another example: application number: 201610199423.X, titled: high-level alley connected drilling hole circulating water cooling system and mine cooling method, the above The patents use mine water only as a cooling source, and additional power is used in the cooling process, so additional energy consumption is still required
