Abstract
Skarn iron ore is an important mineral resource with high mining value.With the continuous progress of prospecting theory and methods,there is great potential for prospecting at Zhangjiakou region.On the basis of previous work,this paper uses the latest 1:25,000 aeromagnetic map to delineate the favorable location of mineralization,carries out high-precision ground magnetic survey and data processing interpretation,detailed dissection was conducted on the magnetic anomaly to determines the borehole position,and use magnetic survey in boreholes to search for blind ore bodies near and at the bottom of boreholes to guide the drilling machine to drill.Through the comprehensive geophysical prospecting method of'air-ground-borehole',the geophysical model is established and inverted by referring to the prospecting experience of Hanxing style iron ore deposit to more accurately determine the location,shape and size of the ore body and provide important technical support for geological prospecting.At the same time,the drilling results also prove the effectiveness of the comprehensive geophysical prospecting method.The amount of resources for this work has increased by more than 18 million tons,and the discovered skarn type deposit is a new type of contact metasomatic iron ore deposit of skarn type at Zhangjiakou region,or even in Hebei province.关键词
