technical field [0001] The invention relates to the technical field of cooling and dehumidification in high-temperature mines, in particular to a shallow cold energy cycle cooling and dehumidification and waste heat utilization system for mine excavation roadways. Background technique [0002] With the continuous increase of mine mining depth, the temperature of mine rock formations continues to rise, so the underground heat damage becomes more and more serious. Especially in high-temperature and high-humidity mining layers, the continuous high-temperature and high-humidity operating environment has a great impact on operators and related equipment, which not only affects work efficiency, but also increases the downhole accident rate.

Especially in high-temperature and high-humidity mining layers, the continuous high-temperature and high-humidity operating environment has a great impact on operators and related equipment, which not only affects work efficiency, but also increases the downhole accident rate

[0003] In order to improve the downhole working environment, at present, the cooling and dehumidification operation of the downhole working environment is usually carried out by means of centralized cooling on the well. The energy consumption is high because of the cooling capacity generated, and the carrier of the cooling capacity (such as frozen water, ice cube / slurry, etc.) has a long transportation distance from the well to the downhole, so there is a large loss of cooling capacity

On the other hand, since the working environment is located underground, it is difficult to discharge the condensation heat generated by local cooling, which may easily lead to secondary heat damage.

In addition, since the current cooling method targets the entire working area, such a cooling treatment method has the problem of high energy consumption

Therefore, the current effect of cooling and dehumidification needs to be further improved.
