为全面系统的评价煤矿井下系统的职业病危害风险,结合煤矿井下系统的主要特点,依据法律法规及实践经验,筛选出煤矿井下系统的主要职业病危害风险因子;利用层次分析法计算各风险因子的权重系数,并进行一致性检验;通过模糊数学理论构建井下系统职业病危害风险评价模型;采用指派法建立相应的风险分级隶属函数;最后通过构建的职业病危害风险评价模型对某矿综采工作面职业病危害风险进行综合评价。根据评价结果,给出优先应采取的防护措施建议,为煤矿的职业卫生管理提供依据。
In order to comprehensively and systematically evaluate the risk of occupational hazards in underground coal mine systems and by combining with the main characteristics of underground coal mine systems, the risk factors of major occupational hazards of underground coal mine systems are screened according to the laws, regulations and practical experiences. The AHP method is used to calculate the weight of each risk factor Coefficient and carry on the consistency test; construct the risk assessment model of occupational hazards in downhole system by using fuzzy mathematics theory; establish the corresponding membership function of risk classification by using assignment method; and finally establish occupational hazards of a mine fully mechanized coal mining face by the risk assessment model of occupational hazards Comprehensive assessment of risk. According to the evaluation results, given priority should be taken protective measures advice for coal mine occupational health management provide the basis.
