Research on the Physiological and Psychological Ability Indexes of Coal Tunneling Workers

Abstract

Studies have shown that accidents caused by human error account for 70-80% of the total number of accidents, and are the primary cause of casualties. In order to reduce the risk of safety accidents and reduce the human-caused accident rate, the evaluation index of safety occupational adaptability of coal excavation workers has been studied. Questionnaire survey method was used to conduct 13 physical and psychological abilities tests on 50 coal tunneling workers, and select the core ability indicators that reflect the mental load of the workers and the individual priority allocation of psychological resources. Secondly, using the Delphi method and the quartile method, the opinions of 20 experts in related fields were sought anonymously, and the main physical and mental ability indicators were screened and filtered through scoring methods. Finally, six indicators of “accuracy, attention, rapid response ability, proficiency, judgment, and foresight” were determined as the main physical and psychological indicators of coal tunneling workers. This study fills up the gap of safety occupational adaptability in the field of mining construction, and has important theoretical value and practical significance.
