邯邢式铁矿是中国著名的铁矿类型之一。近年来,在邯邢地区采用深钻对白涧铁矿低缓磁异常区进行了验证,在孔深592.74～1040.52m处发现了厚度大、埋藏深、规模大、品位高的隐伏邯邢式铁矿,表明该区具有深部找矿的巨大潜力。通过对白涧矿区的综合找矿探测方法技术的应用研究和对白涧铁矿深部隐伏铁矿的预测分析,证实了高精度重、磁方法相结合是寻找该类铁矿最有效的方法。EH-4电磁测深方法通过探测深部隐伏岩体的起伏变化,进而预测和发现盲矿体,是一种间接预测隐伏矿分布的有效方法。针对邯邢地区地表及地下均存在不同程度的重、磁、电干扰,该研究加强了实地干扰源的详细调查和室内资料的相关滤波、圆滑处理、位场的转换、异常正反演解释的研究工作,认为加强赋矿地层、构造、岩浆岩、围岩蚀变和重、磁综合异常“五位一体”的深部综合找矿模式,是寻找邯邢式铁矿深部矿体的有效方法。
Handan Xing iron ore is one of the famous iron ore types in China. In recent years, deep well drilling has been carried out in Handan area to verify the low-anomalous magnetic anomalies in the Baijian iron ore deposit. The buried Hanxing-type iron ore with large thickness, deep burial, large scale and high grade was found at the hole depth of 592.74 ~ 1040.52m, The area has great potential for deep prospecting. Through the application research of integrated prospecting and detecting technology in Baijian mining area and the prediction analysis of the deep concealed iron ore in Baijian iron mine, it is confirmed that the combination of high precision heavy and magnetic methods is the most effective way to find this kind of iron ore. The EH-4 electromagnetic sounding method is an effective method to indirectly predict the distribution of hidden ore by detecting the fluctuation of deep concealed rock mass and then predicting and discovering the blind ore body. In the light of the different levels of heavy, magnetic and electrical interferences on the surface and underground in Handan area, the study has strengthened the detailed investigation of in-situ interference sources and the related filtering and smoothing of indoor data, the conversion of potential fields and the interpretation of abnormal positive inversion Research work, think strengthening ore strata, tectonics, magmatic rocks, wall rock alteration and heavy and magnetic anomaly “five in one ” deep comprehensive prospecting mode, is to find an effective method for the deep orebody of Handan Xing iron ore.
