摘　　要：沙坪沟钼矿位于安徽省金寨县,是在大别山发现的一个特大型隐伏斑岩型钼矿床。在钻探过程中有毒有害气体逸出是经常情况,如果这些气体异常超标,会给施工人员带来危害,影响施工现场进度,增加工程成本。本文通过对钻孔气体组分进行分析、研究,确定钻井内有毒有害气体主要为CO、H2S和氡气,它们的产生与周围岩石断层地质构造以及丰富的地下水环境有关,提出了钻探期间应对措施,实现安全作业。Sha Pinggou Mo deposit located in Jinzhai County of Anhui Province,it is a large concealed porphyry Mo deposit found in the Dabie mountains. In the drilling process , toxic and harmful gases escaping is often the case. If the gas abnormal exceeded, such will bring harm to the construction personnel, influence the construction site progress, increase the project cost. Based on the borehole gas component analysis and research, we found that there exist toxic and harmful gases such as CO, H2S and radon in the drilling, their production related to surrounding rock geological structure and rich groundwater environment, we puts forward the measures to realize safety during drilling operation.
