The Research On The Application Of Low-altitude Magnetic Data Of The Dynamic Delta Wing In The Exploration Of The Duobaoshan Copper Mine

Over the past 20 years with the progress of geophysical exploration methods and technology,the traditional magnetic measurements is turning to high resolution high-precision aeromagnetic survey At present domestic main platform for low-flying unmanned aerial vehicle(uav)airship helicopter dynamic delta wing,etc Dynamic delta wing low magnetic survey method has high working efficiency Strong adaptability Can reduce shallow appropriate cultural interference magnetic source of abnormal interference etc,in recent years to become a quick and effective means of magnetic measurement.Heilongjiang Province Duobaoshan area belongs to hilly area,the terrain ups and downs is bigger,and in the forest swamp diluvial content coverage,rock outcrops,less ground geological and geophysical prospecting task is not easy to expand Much treasure mountain has certain cultural interference is serious,how baoshan mine Tongshan copper mine such as mining of ore deposit,and treasure Lie all river town,town,etc As a result,the ground magnetic survey work results may have large errors Million treasure mountain granodiorite and iron ore rock with strong magnetic,remanence intensity is also stronger;In acidic granite and porphyry magnetic weaker;Tuff and volcanic sedimentary rock with weak magnetic susceptibility;Other lithostratigraphic for weak magnetic;Basic non-magnetic quartz vein rock Therefore,magnetic differences between rock ore for delta wing geophysical basis is provided for a low magnetic survey.In this paper from 2013 to 2015,Beijing institute of geology and mineral resources in heilongjiang million treasure mountain measured power triangle wing magnetic survey data,through a low magnetic survey data processing inversion,combined with the related geological data and other geophysical data summed up the heilongjiang million treasure mountain copper deposits in the metallogenic belt of magnetic prospecting model Specific work and results are as follows:(1)The trike altitude measurement system are introduced,and the measured low magnetic data comparing with other magnetic results,thus confirming advantages of power delta low magnetic measurement work in some complex terrain;(2)This paper briefly introduces the data processing methods of conventional magnetic survey,establishes the theoretical model to verify the potential field separation method and the applicability of boundary identification;(3)The trike low magnetic data processing in the Heilongjiang Baoshan area,through the analytic continuation and trend analysis method of field separation understanding substrate;through a variety of boundary identification technology,contrast that the distribution of faults,the applicability of the understanding of various fault division method in this area.(4)Based on the measured data interpretation results,combined with the geological map and geophysical data analysis of the application of dynamic delta wing at low altitude aeromagnetic data in copper mine area,summed up the metallogenic zone in Baoshan Heilongjiang magnetic ore prospecting model.
