Abstract：
As the depth of coal mining increases, the temperature and humidity of the underground environment also rise, which can negatively impact the physiological health of miners, and may even pose a threat to their safety and lives. However, studies on the neurocognitive mechanisms underlying the relationship between temperature, humidity, and miners\' alertness are scant. This study investigates several research objectives: (A) the differences in reaction time and error rate in different temperature and humidity conditions, which factor has a greater impact; (B) the differences in the levels of Oxy-Hb in different conditions and which factor has a greater impact; (C) the differences of activation degree between different regions of interest; and (D) the differences in the shape of Oxy-Hb time course between different conditions between different regions of interests. The fNIRS was used to measure the activity in 100 participants\' prefrontal cortex in this study. The results showed that both temperature and humidity would lead to decreased alertness of miners, which would not only prolong the reaction time, increase the error rate, and increase the Oxy-Hb concentration, but also lead to increased activation of the prefrontal cortex and greater activation of the right side than that of the left side, the Oxy-Hb time course was different on both sides, and temperature has a greater effect on alertness than humidity.
摘要：
随着煤炭开采深度的增加,地下环境的温度和湿度也升高，这会对矿工的生理健康产生负面影响，甚至可能对他们的安全和生命构成威胁。然而,关于温度之间关系的神经认知机制的研究，湿度,湿度矿工的警觉性不足。本研究考察了几个研究目标:(A)不同温度和湿度条件下反应时间和错误率的差异,哪个因素影响较大;(B)不同条件下Oxy-Hb水平的差异以及哪个因素影响较大;(C)不同感兴趣区域之间激活程度的差异;(D)不同条件下不同感兴趣区域之间Oxy-Hb时间过程的形状差异。在这项研究中，fNIRS用于测量100名参与者的前额叶皮层的活动。结果表明，温度和湿度都会导致矿工警觉性下降，这不仅会延长反应时间，增加错误率，并增加Oxy-Hb浓度，但也导致前额叶皮层的激活增加，右侧的激活比左侧的激活更大，Oxy-Hb的时间过程是不同的双方，温度比湿度对警觉性的影响更大。
