为研究煤矿工人职业健康的发展趋势,促进煤炭企业实施职业健康防护工作,基于知识图谱分析方法,采用CiteSpace软件分析中国知网(CNKI)和Web of Science(WoS)核心数据库中收录的近20年煤矿工人职业健康文献的关键词聚类及突现.研究结果表明:煤矿工人职业健康研究可分为职业健康危害因素、职业病及职业相关疾病三维度.职业相关疾病主要体现在行为和身心疾病、心脑血管疾病与代谢性疾病及慢性非特异性呼吸系统疾病3个层面;与职业病相比,职业相关疾病多呈现为"多因一果"特征,确诊难度更大;基于高频词突现特征,尘肺、听力损失、心理压力、高血压等是煤矿工人健康的主要威胁,此类健康问题与职业暴露有关,风险评价与管控是应对危害的重要措施;新兴研究热点为职业相关疾病的成因与防范,及职业健康与脑科学、智能化等领域的交叉研究.
Knowledge graph analysis of research progress in occupational health of coal miners
To investigate the development trend of occupational health of coal miners and promote the implementation of occupational health protection in coal mines.Based on the knowledge graph analysis method,CiteSpace software was used to conduct the keyword clustering and emergence of coal miners'occupational health literature included in the core databases of China National Knowledge Infrastructure(CNKI)and Web of Science(WoS)in the past 20 years.The results indicated that coal miners'occupational health research topics were divided into occupational health,occupational hazard factors,and career-related diseases.Occupational-related diseases focused on behavioral and physical diseases,cardiovascular and cerebrovascular diseases metabolic diseases,and chronic non-specific respiratory diseases.Compared with occupational diseases,occupational-related diseases had the characteristics of'multiple causes and one effect',causing much more difficulty in diagnosis.Pneumoconiosis,hearing loss,psychological stress,and hypertension were the main factors threatening coal miners'health.Moreover,such health issues were associated with occupational exposure,and risk analysis and control were important strategies to deal with hazard factors.The emerging research hotspots were the cause and prevention of occupational-related diseases,and the multi-discipline research of occupational health,brain science,and intelligence.
