综合信息技术预测辽宁大台沟铁矿远景资源量

摘要

Based on a detailed study on the geology and geophysics of the Dataigou iron deposit,the relationship between the gravitational,magnetic,electric and logging anomaly information and the morphology of orebody is analyzed.The orebearing coefficient and correction coefficient of the deposit are calculated,with comprehensive information analysis technique and surveyed physical parameters of rocks (ores) combined with existing drilling data.Using the RGIS quantitative inversion method for magnetic deposits,the boundary and decurrent depth of orebodies are forecasted.The perspective resources of the Dataigou iron deposit are also estimated.%在研究大台沟铁矿地质、地球物理特征的基础上,分析了重、磁、电及测井等异常信息与矿体形态的关系.采用综合信息分析技术,并利用实测的矿区岩(矿)石物性参数,结合已有钻孔资料,计算出大台沟铁矿体含矿系数及校正系数.采用RGIS磁性矿床定量反演方法预测了矿体边界及下延深度,并估算了大台沟铁矿远景资源量.
