Abstract

Objective

In order to reduce the impact of heat damage and reduce the incidence of accidents, this study will conduct regression analysis and cognitive ability test to quantify the relationship between temperature level and miners' physiological state, and monitor the impact of temperature on miners ' cognitive ability and working state.

Methods

Controlling different temperature levels as variables, with the help of PhysioPlux physiological recorder, two physiological indexes of heart rate variability and skin electricity were selected to study the physiological changes of miners caused by different temperature levels, and the influence of temperature on cognitive ability was studied based on cognitive ability test.

Results

(1) With the increase of temperature, the HRV time domain indexes RMSSD and SDNN of the subjects increased at different rates. When the temperature was increased again, the two physiological indexes decreased at a faster rate within the normal range. The skin conductance SC value of the subjects increased with the increase of temperature, the linear regression equation between different temperature levels and RMSSD / SC was established. (2) The cognitive response speed increases first and then slows down with the increase of temperature. The cognitive accuracy AC decreases with the increase of temperature. The increase of temperature reduces the cognitive ability.

Conclusion

Determining the physiological threshold and monitoring the status of coal miners is helpful to establish an underground safety early warning system and minimize the risk of coal mine accidents.

深部工作面热环境对矿工生理和认知能力的影响研究

目的为了减少热损伤的影响，降低事故的发生率，本研究将进行回归分析和认知能力测试，量化温度水平与矿工生理状态的关系，监测温度对矿工认知能力和工作状态的影响。方法控制不同温度水平为变量，借助physioplus生理记录仪，选择心率变异性和皮肤电两个生理指标，研究不同温度水平下矿工的生理变化，并在认知能力测试的基础上，研究温度对认知能力的影响。被试HRV时域指标RMSSD和SDNN均有不同的上升速率。当温度再次升高时，两项生理指标在正常范围内下降速度更快。被试皮肤电导SC值随温度升高而升高，建立不同温度水平与RMSSD / SC之间的线性回归方程。(2)随着温度的升高，认知反应速度先升高后减慢。认知准确度AC随温度升高而降低。温度升高会降低认知能力。结论确定生理阈值，监测矿工状态，有助于建立井下安全预警系统，最大限度地降低煤矿事故风险。

期刊介绍： Physiology & Behavior is aimed at the causal physiological mechanisms of behavior and its modulation by environmental factors. The journal invites original reports in the broad area of behavioral and cognitive neuroscience, in which at least one variable is physiological and the primary emphasis and theoretical context are behavioral. The range of subjects includes behavioral neuroendocrinology, psychoneuroimmunology, learning and memory, ingestion, social behavior, and studies related to the mechanisms of psychopathology. Contemporary reviews and theoretical articles are welcomed and the Editors invite such proposals from interested authors.
