摘要: 坦桑尼亚联合共和国某金矿,在没有测井设备的情况下,利用SM-30磁化率仪,直接测定钻孔岩芯岩(矿)石的磁化率数值,将钻孔深度与该深度处对应的磁化率数值绘制成类似于测井曲线,根据磁化率参数的曲线特征,进行岩性层位划分,确定金矿层的走向,经与钻孔地质柱状图对比,该方法效果很好。

Abstract: In a gold mine of Tanzania,Sm-30 magnetic susceptibility device was used to directly measure the magnetic susceptibility values of drilling core rocks (ores)in the absence of logging equipment;the depths of the drill hole and the magnetic susceptibility val-ues corresponding to these depths were plotted similar to well logs.According to the curve characteristics of the magnetic susceptibility parameters,the division of lithologic horizons was conducted,and the strike of the gold ore bed was determined.A comparison with the drill hole geological columnar section shows that this method is quite effective.
