为解决制约我国煤炭工业向深部发展的热害难题，以五矿己采区为工程背景，利用系统工程理论中模糊综合评价分析方法验证矿井通风系统的合理性，表明仅仅依靠通风来降低作业地点的环境温度是不够的。矿井采取改善矿井通风系统、减轻局部热源对新鲜风流的加热作用、加强井下工人劳动保护、采取人工制冷措施等进行综合治理，大大地改善了五矿作业地点的热环境。%To solve the problem of heat disaster restricting the development of China's coal industry to the deep,taking No.5 mining area as engineering background,the paper has verified the rationality of mine ventilation system by using fuzzy comprehensive evaluation of system engineering theory.Results show that the comprehensive treatment such as improving mine ventilation system,reducing local heating of fresh air flow,strengthening the labor protection of underground workers and taking artificial refrigeration measures have greatly improved the thermal environment of operating location in No.5 Colliery.
