摘　　要：以广西大厂矿区内埋深超过800 m的95号锌铜矿体为研究对象,采用快速地气采样装置和ICP-MS分析技术对大深度隐伏多金属矿进行地气测量试验。结果表明,矿体上方Zn、Cu地气异常超过背景值3倍以上,Pb、As、Cd、Bi、Co、Cs、Mo、Rb等也呈现显著异常,证实采用地气测量探测埋深超过800 m的大深度隐伏矿体是完全可行的。With No. 95 zinc-opper ore body over 800 m in depth in the Dachang zinc-copper deposit of Guangxi as the research object, the authors carried out experiment on geogas survey by using dynamic geogas sampling device and ICP-MS analysis technology for exploration of large depth concealed polymetallic deposit. The results show that the geogas anomaly values of Zn, Cu elements above the ore body are 3 times higher than their background values, and Pb, As, Cd, Bi, Co, Cs, Mo, Rb and other elements also show significant anomalies. These data prove that using geogas survey to explore the large depth concealed ore bodies whose depth exceeds 800 m is completely feasible.
