摘　　要：为更高效地将地气法应用于地质找矿过程中,着重强调了矿体关键特征参数的作用,并使用QMU方法确立了矿体的关键特征参数。在实践中以某铅锌矿为例,在埋深50 m的隐伏矿体上方发现了较为明显的矿体关键特征参数异常,与已知矿体位置完全吻合,显示了地气法找矿中的关键特征参数在隐伏矿勘查中的关键指示作用。In order to apply the geogas method to the ore prospecting process more efficiently,the function of mineral body characteristic parameters is emphasized,and the characteristic parameters of mineral body are established by QMU method.In practice,taking a lead-zinc mine as an example,the characteristic parameters of the relatively obvious ore body were found above the hidden ore body with a depth of 50 m,which is completely consistent with the location of the known ore body.It is shown that the characteristic parameters of geo-gas prospecting are the key indicators in the exploration of hidden deposits.
