介绍了利用自行研制的便携式X射线荧光分析仪在大红山铜矿井下用X荧光取样分析代替人工打点取样分析,现场原位测量岩壁Cu、Fe品位的应用情况。采用的仪器是由238Pu同位素源、正比计数管、多道脉冲幅度分析器、便携微机系统等组成的能量色散型分析仪,具有自动稳谱功能。研究结果表明:X荧光取样的原矿品位与化学分析结果相比,Cu相对误差在10%以内的合格率达到95%,Fe相对误差在5%以内的合格率为90%,完全能满足矿山生产的要求。

Mining activities have created huge uncovered slopes, large areas of gangue ground and extensive tailings dams. This paper presents the environmental geochemistry of mining activities in Panzhihua region. The selected elements (Ti, V, Mo, Ni, Pb, Cu) show similar distribution patterns of concentration anomaly in topsoil. These concentration anomalies are located in V-Ti-magnetite slope, gangues dam and coal mine. The distinction between anthropogenic contamination and natural background is made available by the use of the enrichment factor in this study area. The anomalies of EF were smaller than that of concentration. The results from EF show that the selected elements anthropogenic pollution (EF>1) in topsoil were located in both the coal mining area and the V-Ti-magnetite mining area. In addition, the pollution sources of selected elements came from V-Ti-magnetite, slag, gangues, coal and other pollutants from mining activities.
