一、引言矿井微气候是指近地大气在某种动力(自然的、人为的)作用下,经过地下特有的构筑环境而形成的小气候。随着开采规模的扩大和采深的增加,矿井微气候变化规律的研究有着十分重要的意义,尤其是高温微气候的形成与发展将直接影响人们的开采环境和劳动生产率。苏联学者认为,空气的温度超过标准1℃,工人的劳动生产率便降低启-8％,南非在1924年第一次出现井下高温人身事故后,对矿井高温微气候的研究有相当的重视。我国在50年代,矿井降温只涉及个别矿井,所出现的高温问题也不是深度所致。60年代
I. INTRODUCTION Mine micro-climate refers to the micro-climate formed by the near-surface atmosphere under the action of a certain kind of power (natural and man-made) through a unique underground construction environment. With the expansion of mining scale and the increase of mining depth, the research on the law of microclimate change in mines is of great significance. In particular, the formation and development of high-temperature microclimates will directly affect people’s mining environment and labor productivity. Soviet scholars believe that the air temperature exceeds the standard of 1°C, and the labor productivity of workers is reduced by -8%. After South Africa first encountered underground high temperature personal accidents in 1924, it paid considerable attention to the study of mine high-temperature microclimate. In China, in the 1950s, the cooling of mines only involved individual mines, and the high temperature problems were not caused by the depth. the 60’s
