摘要
简述矿床地质特征和开采技术工艺,详细叙述井下氡的特点,指出采用压入式通风方式、实行分区通风、灵活运用各种探矿手段、坚持探采结合以及密闭氡源、减少污染、改进采矿工艺是提高通风排氡效果的有效途径。提出氡和氡子体浓度合格率指标为80％—85％是较为经济合理的。
The geological features of the Fuzhou uranium deposits and mining technological characteristics are briefly described in this paper. The characteristics of underground radon problems are discussed. The ways to increase the effects of underground ventilation for radon removal in uranium mines are presented.
