基于相变降温技术的矿井局部热害控制研究

摘要

文章在详细总结国内外高温矿井局部热害成因和控制方法的基础上，提出了极细雾粒相变降温技术。通过流体力学数值模拟软件CFD，对煤矿井下高温硐室的相变降温进行数值模拟研究。结果表明，经过相变降温后，硐室温度降低到人体可以接受的范围之内，利于煤矿的绿色、安全、高效、和谐发展。%The paper based on summarized the sources of the coal mine thermal damage and control measures at home and abroad in detail, and the technology of phase-change cooling of very fine mist is putted forward. Computational Fluid Dynamics FLUENT is used to simulate the air environment cooling of high temperature chamber. The results showed that the temperature of chamber could be dropped to an accept-able range by human beings. It's beneficial to the Green, safety, high efficiency and harmonious development of coal mines.
