AI Technical Summary
Existing liquid nitrogen cooling technology is difficult to apply to the multi-point and multi-line cooling needs of deep mining areas in metal mines, and it does not take into account the issues of moisture prevention, corrosion prevention and cold loss control during long-distance vertical transportation. At the same time, there is a risk of oxygen deficiency and suffocation caused by nitrogen accumulation.
A modular liquid nitrogen cooling system is adopted, including a ground liquid nitrogen supply unit, an insulated and moisture-proof transportation unit, an underground storage and distribution unit, and a stope heat exchange and safety monitoring unit. Combined with a vacuum insulation layer and a micro-positive pressure dry nitrogen barrier layer, it is equipped with an intelligent control unit to achieve multi-point and multi-line synchronous cooling and safety monitoring.
It effectively isolates high-temperature and high-humidity environments, reduces cold loss, achieves precise cooling, prevents the risk of nitrogen asphyxiation, and supports the refined management and production decision-making of mining enterprises.
