新型矿井降温系统的设计及应用

Design and Application of New Mine Cooling System

阐述了高温矿井对生产的影响,设计了一种防治矿井热害的系统。该系统与采用局部冷却降温方式相比,具有系统能效比(COP)较高、低投资、制冷设备集中在地面、易于设备安装维护和管理、无污染等特点。利用地面预制低温空气,通过现有的通风系统输送到井下,达到预防、消除矿井热害的目的。运用模拟软件ANSYS对进口空气进行了温湿度模拟并且在华丰煤矿进行现场实践应用,进一步验证了该系统的可行性。

The influence of high temperature mine on production is expounded, designed a system to control mine thermal damage. The system is compared to the local cooling mode, with the system energy efficiency relatively high, low investment, refrigeration equipment is concentrated on the ground, easy to install, maintenance and management, no pollution and other characteristics. Using ground prefabricated low temperature air, through the existing ventilation system to the underground, to achieve the purpose temperature system. of eliminating mine heat damage. Simulation software was used to simulate the import air and humidity and Huafeng coal mine for field practice, further verify the feasibility of the
