摘　　要：矿山开采作业进入深部区域,作业环境高温导致工作条件恶化,严重影响劳动者身心健康和降低作业效率。针对凡口铅锌矿井下开采条件和开采工艺,通过矿区地表气候条件、矿井原岩地温参数和矿内气候条件等开采热环境调查和数据统计,得出围岩放热、矿井热水、矿岩放热、空气自压缩放热、机械放热等五类产热方式为导致井下高温热害的主要因素,采用正算法和逆算法来计算工作面冷负荷,为矿山深部开采热害防治机械制冷提供参数依据。The high temperature of the working environment leads to the deterioration of working conditions with mining operations enter deep areas,which seriously affects the physical and mental health of workers and reduces working efficiency.In Fankou Lead-zinc Mine underground mining conditions and mining process,through the hot mine environment investigation and data statistics such as the mine surface conditions,the original rock geothermal parameters and mine inner conditions,and it is concluded that the heat release of surrounding rock,the features of mine water,heating,air compression heat,heating machinery,such as the five types of heat production way are the main factors leading to thermal damage environment,the direct and inverse methods to calculate the cooling load of the working face,for mine deep mining mechanical refrigeration of the thermal pollution prevention provide parameters.
