摘　　要：为了进一步控制矿区的构造发育及矿体赋存情况,采用三维地震勘探技术,对旗杆楼铁矿进行了勘探,本次三维地震数据采集共计完成地震线束40束,完成生产物理点3444个(其中井炮3108个,可控震源点336个),完成满覆盖面积6.41 km^(2)。研究得出,区内矿体的分布位置、埋深及形态,查明了区内断层分布及特征,解释断层32条,均为正断层,区内陷落柱发育情况及特征,共识别出陷落柱7个,最大直径为260 m,区内古河床、岩浆岩侵入体等的位置及范围。研究为铁矿勘探开发钻探提供了依据。In order to further control the structural development and occurrence of mine bodies in the mining area,3D seismic exploration technology was used to explore the Qiganlou iron mine.This 3D seismic data acquisition completed a total of 40 seismic harnesses,3444 production physical points(including 3108 well guns and 336 controllable source points)and a full coverage area of 6.41 km^(2).According to the study,the distribution location,burial depth and shape of the mine bodies in the area are delineated,and the distribution and characteristics of the faults in the area are identified.32 faults are normal faults,and the development and characteristics of the collapse columns in the area are explained.A total of 7 collapse columns are identified,with a maximum diameter of 260 m.The location and scope of the ancient river bed and magmatic rock intrusion in the area are identified.The study provides a basis for iron mine exploration and development drilling.
