Abstract

Abstract: The subjective fatigue evaluation method was used to investigate and study the physical fatigue and mental fatigue of coal mining workers in a mining company of Shaanxi, and to know the work content and rest time of workers. Through data analysis with SPSS software, obtain the fatigue value of coal miners, and analyzes the cause of fatigue, put forward corresponding suggestions and solution based on the actual situation. The results show that the physical fatigue of coal miners mainly occurs in the waist, shoulders, forearms and hind legs, noise fatigue and visual fatigue is the main factors that affect workers' mental fatigue. Therefore, it is recommended to optimize the operation of miners to maximize the working environment of workers and optimize the production process and management system. The purpose is to reduce the physical and mental fatigue of coal miners, prevent human error and improve the safety of the production process.

Key words: coal miners, physical mental fatigue, operational environment, subjective fatigue evaluation
