The Application Of Magnetic In The Exploration Of SiJiaYing Iron Ore

The aviation magnetic measurement of Hebei TangShan LuanXian SiJiaYing ironmine is in the80s,and then in allusion to the aeromagnetic anomalies the magneticmeasurement or iron ore exploration is done, and it has several medium-large iron ores.Inorder to expand the reserves, outside the SiJiaYing iron ore we did the magneticprospecting work, main purpose is in foundation of the full collection, study of existingmaterial, outside SiJiaYing iron ore screening some division for further verification toexpand the ore-searching prospects, determining the distribution of iron ore resourcesoutside the SiJiaYing iron ore.The magnetic prospecting decorate three study areas.First of all in the ground usingthe high accuracy electronic magnetic instrument field data acquisition, and the dataprocessing of observation data are magnetic slyness and analytical continuation andreduction to the pole, the application of the modern mapping software draw the analysisdiagrams of magnetic data; After considering the formation, structure material, physicalproperty material and modern metallogeny, do the qualitative and quantitative interpretationof the processing data. and in the expected mineralization districts to drillingverification,According to the results of the drilling revealed, and with the typical profilethrough the center of the abnormal we do forward and inverse simulation interpretation, tomake sure the abnormal section that there is the prospects of prospecting, Through theinvestigation of the SiJiaYing iron ore resources and the interpretation of the groundmagnetic data, the comparison and analysis of the existing material each other, in dataprocessing and in the process of forward and inverse interpretation, using differentparameters, parallel processing results, looking for the effect of the treatment with differentparameters, studying the relationship between the magnetic anomaly characteristics of theAnshan type iron ore and iron ore resources, on the basis of research established thegeological and physical geography prospecting model, provide with the reliable basicmaterial for iron ore resources in the region and ore-prospecting technical basis for laterfurther prospecting.On the basis of the full study of the magnetic characteristics, there are9magneticanomalies of this area to be inference and interpretation,3magnetic anomalies of thedrilling. in the three bore drilling of QianSuoYing they are all reached orebodies, andpreliminarily determines the thickness of the ore bodies; To estimate this is medium-sized magnetite ore. In southern of SiJiaYing, DaLanTuo with Quaternary covered739metersfound that22m thick higher grade layer of the magnetite, this anomaly dimension is largeand there may is a large iron ore in the further exploration.Magnetic prospecting to verify the aeromagnetic anomalies of known is a veryeffective method.
