安庆铜矿三号矿体地球化学特征及用其指标预测盲矿的效果

Geochemical Features of the No.3 Orebody at the Anqing Copper Mine and Using Its Evaluation Index to Predict Buried Ore

为开展矿区外围找矿,研究了安庆铜矿已知三号矿体的地球化学特征,用工业指标法及联合指标法分带制图,建立异常评价指标,用多种方法研究类比异常,预测盲矿体方位,经钻探验证取得了较好的见矿效果.

For the purpose of unfolding an exploration activity in the peripheral region of the Anqing copper mine, chemical features of the No.3 orebody of this mine (being proved) have been studied. Theanomaly zoning map drawn by industrial index method and combined index method was used to establishan anomaly evaluation index. Then in turn we used this index in the peripheral region to look forburied orebodies. Anomalies were classified by analogue analysis and the positions of buried orebodieswere known in advance. Anomalies predicted in this way have been tested by drilling with positiveresults.
