Development of an active cooling vest for deep mines workers

矿产资源枯竭迫使采矿公司为了继续开采而挖得更深。 超深井的数量正在增加，尽管普遍的工作条件，如高 温度和高湿度水平。在这些条件下，矿工只能工作很短的时间，导致生产率非常低。因此，冷却装置可以代表这个问题的创新解决方案。然而，该系统必须保持轻便和灵活，以不妨碍工人的流动性，不像流体循环系统，在这个项目中没有考虑除了比较的目的。通过使用特定的导电纱线，Jannatec Technologies希望通过制造能够重现Peltier效应的导电纺织品针织结构来开发一种主动冷却护套。在确定和表征合适的材料后，将制作背心原型，然后进行测试以评估热性能。该项目将是CTT集团，Cégep de St-Hyacinthe和Jannatec Technologies之间新联盟的结果，因为他们将首次合作。这种发展将导致采矿效率的提高和矿石开采成本的降低，这将有助于促进采矿业，这是加拿大经济的一个重要部门。

Mineral resources depletion is forcing the mining companies to go deeper in order to continue their extraction. The number of ultra-deep mines is increasing despite the prevailing working conditions such as high temperature and high humidity level. With these conditions, miners can only work for short periods which lead to very poor productivity rate. Cooling devices coul, therefore, represent an innovative solution to this issue. However the system must stay light and flexible to not impede the worker's mobility, unlike fluid circulating systems which are not considered in this project aside for comparison purposes. By using specific conductive yarns, Jannatec Technologies want to develop an active cooling jacket by fabricating conductive textile knitted structure able to recreate the Peltier effect. After identifying and characterizing suitable materials, a vest will be prototyped and then tested to evaluate the thermal performance. This project will be the result of a new alliance between CTT Group, Cégep de St-Hyacinthe and Jannatec Technologies since they will be working together for the first time. Such development would result in an increase of mining efficiency and a lower cost of ore extraction which would help boosting the mining industry which is an essential sector for the Canadian economy.
