Abstract:

To make the problem that plagues the development of occupational health in China with the high incidence of mining pneumoconiosis, this study explored a set of effective prevention models for mining pneumoconiosis. Based on GT, interview data from 24 experts and text extracted from 20 documents were processed using open coding and selective coding under the Grounded Paradigm. This study formed 4 core categories, and established a four-level comprehensive prevention theoretical model of mine pneumoconiosis in the "1+3" pattern. According to outcomes of open coding and selective coding, the distribution characteristics and frequency of occurrence of each code were statistically analyzed. The results show that zero-level prevention (laws and regulations, social functions, government functions) provides top-level design; primary prevention (engineering technology management, health management organizational behavior, individual health self-management) is a prerequisite, secondary prevention (employee health management, workplace occupational health evaluation) plays a facilitating role, and tertiary prevention (social participation, post-illness self-management, medical protection, rights and interests protection) is the last line of defense. The four core categories form four-level prevention model for occupational pneumoconiosis, providing a guiding framework for developing strategies to prevent occupational pneumoconiosis in mines.
