Abstract: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.
