【摘要】 黄河北煤田内发育煤、煤层气、页岩气等能源矿产,近年该厚覆盖区煤系下取得富磁铁矿深部找矿重大新发现。在系统分析该煤田成矿地质条件和多种矿产资源勘查成果的基础上,探讨了区内多矿产成矿地质作用,总结了各矿产之间的联系。面临巨厚覆盖层深部找矿难题,基于以往勘查经验,提出了多种矿产协同勘查的找矿思路,总结了重磁电震多种地球物理信息融合的找矿方法,建立了"资料融合分析+重磁联合反演+电震层界约束+钻探深部验证"的多手段综合探矿体系,为相似地区找矿提供指导与借鉴。更多还原

【Abstract】 In the Huanghebei coalfield have developed coal,CBM and shale gas etc energy minerals.In recent years,under the thick overburden coal measures,through deep part prospecting has important new findings of high-grade magnetite.On the basis of systematic analysis of the coalfield ore-forming geological condition and multiple mineral resources exploration results have discussed multiple mineral ore-forming geological processes,summarized relationship between minerals.Facing the extra-thick overburden covered deep part prospecting hard nuts,based on previous exploration experiences have proposed multiple minerals collaborative prospecting thinking,summarized prospecting method to fuse gravitational,magnetic,electric and seismic etc multiple geophysical information together;established"data integration analysis + gravitational magnetic cooperative inversion + electro-seismic layer interface restraint + drilling deep part verification"multi-means integrated prospecting system and provided guidance and reference for prospecting in similar condition areas.更多还原
