Abstract

The invention discloses an efficient and energy-saving mine cooling and water supply system, comprising an air-cooled heat exchange unit, a water-cooled refrigeration unit, a high and low pressure heat exchange unit, a cooling air conditioner and an electric control system. The air-cooled heat exchange unit and the water-cooled refrigeration unit are respectively It is connected with a replenishing water tank, which is used to connect tap water. The air-cooled heat exchange unit and the water-cooled refrigeration unit can communicate with each other through pipelines and valves. Both the air-cooled heat exchange unit and the water-cooled refrigeration unit can exchange heat with the downhole through pipelines and valves. The pipes are connected, and the downhole heat exchange pipe located in the underground roadway is connected with a cooling air conditioner and a high and low pressure heat exchange unit for cooling the main roadway. The lower end is respectively connected with a cooling air conditioner, and the air-cooled heat exchange unit, the water-cooled refrigeration unit, the high and low pressure heat exchange unit and the cooling air conditioner are respectively electrically connected with the electric control system. The invention ensures the safety and stability of the well cooling system and reliable water supply for cooling and production.

Description

technical field [0001] The invention relates to the technical field of mine cooling systems, in particular to an efficient and energy-saving mine cooling and water supply system. Background technique [0002] With the increase of the mining depth of mineral resources, the temperature of the original rock continues to rise, and the high temperature heat damage of the mining and excavation face is becoming more and more serious. Resulting in the further deterioration of the thermal environment in the well. The underground thermal environment of high temperature and high humidity not only reduces the production efficiency of coal mining, but also seriously endangers the physical and mental health of the workers. [0003] At present, the measures of increasing the air volume are difficult to alleviate the problem of high temperature heat damage in the deep well working face, and it is necessary to combine the measures of artificial cooling and cooling. In the realization of ar...
