摘　　要：贵州含煤层位多,自上震旦统-第四系有9个层位产煤。在系统收集全省含煤岩系含铀性资料的基础上,结合采集样品,环境地表γ辐射剂量率和土壤氡气浓度含量测量,依据相关规程规范,评价了含煤岩系含铀性核素对环境的影响。研究认为,贵州含煤岩系放射性铀对各区的环境影响不同,煤层厚、煤质好的区域,放射性铀含量相对低;煤层薄、煤质差的区域,放射性铀含量相对高,但大部分地区的环境放射性水平较低,整体影响较小。From upper Sinian to Quaternary have totally 9 coal producing horizons in the Guizhou Province. On the basis of coal-bear- ing strata uranium mineralization information from whole province, combined with sample acquisition, environmental surface ~ radia- tion dose rate and soil radon concentration and content measuring, according to related codes and specifications have assessed coal- bearing strata uranium mineralization nuclide impact on environment. The study has considered that the radioactive uranium impact on environment from coal-bearing strata is different. In the areas with thick coal seam and high coal quality have relatively low radioactive uranium content; while in the areas with thin coal seam and poor coal quality have relatively high radioactive uranium content; but in most areas have low environmental radioactivity level, thus less overall impact.
