某煤矿1.20Mt/a技术改造项目职业病危害控制效果评价

目的通过对某煤矿1.20 Mt/a技改项目职业病危害控制效果评价,探讨控制技术及防护措施。方法通过职业卫生调查法、职业卫生检测法、检查表分析法等方法进行定性和定量评价。结果该项目总平面布局、职业病防护设施、个人使用的职业病防护用品、应急救援、卫生辅助用室设置、职业卫生管理等均符合国家卫生标准。该项目生产过程中产生粉尘、噪声、有毒有害气体(CO、NO、NO2、SO2、H2S)等职业病危害因素,其中部分岗位粉尘和噪声浓度(或强度)超标。结论该项目职业病危害控制措施可行、有效,但部分岗位仍需加强治理。

Evaluation on control effect of occupational hazards in 1.20 Mt/a technical innovation project of a coal mine

Objective]To evaluate the control effect of occupational hazards in 1.20 Mt/a technical innovation project of a coal mine,study the control technology and protective measures.Methods]The qualitative and quantitative evaluation was conducted by occupational health investigation,occupational health detection and checklist analysis.Results]The general layout,occupational protective facilities,individual protective equipments,emergency rescue,health auxiliary rooms and occupational health management met the national health standards.The main occupational hazard factors of this project were dust,noise,toxic and harmful gases(CO,NO,NO2,SO2 and H2S).The concentration(intensity) of dust and noise in some positions exceeded the standards.Conclusion] The control measures of occupational hazards in this project are feasible and effective,but it is necessary to strengthen the governance in some positions.
