Research on Issues in the Stone Crushing Workshop of LB Company Based on Human Factors Engineering

Abstract

This paper presents a systematic study of the operational environment in the stone crushing workshop of LB Company in northern China, based on principles of human factors engineering. The study first identified key environmental issues within the workshop through a combination of field measurements and questionnaire surveys. These issues included excessive noise levels, elevated dust concentrations, inadequate lighting, and a lack of temperature and humidity control. Such environmental factors have a significant adverse impact on employee health and work efficiency. In particular, the high noise levels, dust pollution, poor lighting, and unfavorable microclimate conditions in the workshop are conducive to worker fatigue, respiratory diseases, and other health problems. Based on the findings, improvement standards were established for environmental factors such as noise, dust, lighting, and temperature and humidity control in the crushing workshop. Drawing on human factors engineering principles, proposed improvements include noise source isolation, dust control, lighting optimization, and climate regulation, all aimed at enhancing employee health and work comfort. The study demonstrates that a systematic human factors engineering approach can significantly improve the environmental quality in stone crushing workshops, providing effective theoretical support and practical reference for industries such as stone crushing and mineral processing.
