摘　　要：通过对某大型深井铁矿井下作业环境的综合测试,掌握了该矿主要作业面的粉尘、有毒有害气体、氡及其子体辐射危害等方面的实测数据。数据分析发现一些凿岩工作面、采矿工作面的粉尘浓度超标,井下主要作业点有毒有害气体浓度低于国家工业卫生标准限定值,但是部分作业点由于通风效果欠佳,氡及其子体辐射水平超过国家卫生标准,井下通风排污效果有待进一步加强。Based on the underground work environment test of a large iron ore mine,some measured data on the dust of major operating surfaces are under control, such as toxic and harmful gases,radiation hazards of radon and its daughters and so on.Although the mine major working spots concentration of toxic and harmful gases are lower than the limit value of industrial hygiene standards,dust concentration of some drilling faces and mining spots exceeds that of the standards,meanwhile the radiation level of Radon is far beyond our country＇s hygiene standard due to poor ventilation of some parts of the mine operating points,so the efficiency of underground mine ventilation needs to be further strengthened and raised.
