Pre-evaluation of Occupational Hazards in New Mining District of A Coal Mine

目的对某煤矿拟新建矿区生产过程中可能产生的主要职业病危害因素进行识别、分析和评价,并提出相应的职业病防护措施,以预防职业病,保护劳动者健康。方法依据国家相关标准,采用类比法和定量分析法相结合的原则进行定性、定量评价。结果拟建项目的选址、总平面布置、职业病防护措施、建筑卫生学、职业卫生专项经费概算等设计基本符合卫生学要求;职业卫生管理、应急救援、个人防护等依托总公司,也基本能够符合相关职业卫生标准的要求。经类比分析,项目生产过程中可能产生的毒物和粉尘能够符合国家卫生标准要求;采取有效的职业病防护措施和个人防护措施后,可以减轻噪声对作业工人健康的危害。结论某煤矿拟建项目属职业病危害严重的建设项目,但生产过程中产生的职业病危害因素是可以预防和控制的。

[ Objective ] To identify, analyze and evaluate the potential occupational hazards of the process of production in new-buih district of coal mine, and provide measures for occupational diseases prevention so as to protect workers＂ health. [ Methods] Accord- ing to related national standards, the analogy and quantitative analysis method were adopted for qualitative and quantitative evalua- tion. [ Results] The designs, such as site selection, general layout, protective measure of occupational disease, buildings hygiene and occupational health special-purpose funds estimate, were basically consistent with hygiene requirements. Occupational health management, emergency rescue and individual protection, etc were also basically consistent with the occupational hygiene requirements. By analogical investigation, the poisons and dust which were generated in the process of production were in line with the national hygiene standards. Moreover, hazards of noise on workers＇health could be lessened after the effective protective measure of occupational diseases and individual protective measure were applied. [ Conclusion] The new mining district is a serious occupational hazard project, but the hazards generated in the process of production can be prevented and controlled.
