辽宁贾家堡子铁矿床磁力剖面2.5D反演模型计算应用

An Application of Magnetic Profile 2. 5D Inversion Model in Jiajiapuzi Iron Ore Deposit in Liaoning Province

于辽宁贾家堡子铁矿区内开展异常圈定、矿致异常精测以及2. 5D反演模型建立、验证及参数校正工作,且建立的模型显示预计见矿深度与实际见矿孔深度相差2 m左右,模拟矿体与钻孔控制矿体几乎重合一致,该模型参数较为合理,对矿区钻孔设计以及矿体推断具有精确的指导意义。

Based on the work of abnormal delineation, we have made an accurate measurement of ore causing anomalies, including 2.5D inversion model establishment, verification and parameter con＇ection. Our work found out that the error was around 2 m between the expected ore depth and the actual mining depth. The simulated ore body was almost identical with the drilling controlled body. The parameters of this model were reasonable, and it has precise guiding significance for drilling design and ore body inference.
