液氮降温系统在煤矿的运用

Application of Liquid Nitrogen Cooling System in Coal Mine

近年来在煤矿矿井采掘深度不断加深的影响下,出现的矿井热害问题逐渐称成为相关人员思考的重点问题。当前阶段,较为常用的下行通风降温形式一般只可以控制工作面温度为31℃,然而这并不能从实质上解决高温热害的问题。因为液氮降温系统是现阶段应用较为普遍的一种全新技术,同时也具备降温以及防灭火的功效,为此,在相关领域得到广泛的推广。

in recent years, under the influence of the deepening of the mining depth of coal mine, the problem of heat damage appears gradually called the key issue of the relevant personnel thinking.The current stage, more commonly used in the form of cooling ventilation can only control the working surface temperature of 31 degrees, but this does not solve the problem of high temperature heat damage in essence.Because liquid nitrogen cooling system is a new technology which is widely used in the present stage, it also has the function of cooling and fire prevention.
