摘　　要：矿石开采遗留了大量的采空区,严重威胁矿山的生产安全和周边群众的生活安全。为消除安全隐患,某铁矿通过现场勘探、制定综合探测方案、实施辅助工程,应用地球物理探测、钻孔探测、三维激光扫描技术实现了揭露采空区及隐伏采空区的三维综合探测,准确掌握了空区的三维赋存形态、大小、空间坐标,为空区治理、残存资源回收设计、生产计划调整和储量动态管理等后续工作提供了高精度基础数据和科学依据。A large number of mined-out areas are left over from ore mining,which seriously threat⁃ens the production safety of the mine and the life safety of the surrounding people.In order to eliminate po⁃tential safety hazards of an iron ore,3D comprehensive detection of exposed goaf and hidden goaf is real⁃ized through on-site exploration,formulation of comprehensive detection plan,implementation of auxiliary projects,and application of geophysical detection,borehole detection,and 3D laser scanning technology.The three-dimensional occurrence shape,size,and spatial coordinates of the empty area are accurately grasped,which provide high-precision basic data and scientific basis for the follow-up work such as empty area management,residual resource recovery design,production plan adjustment,and dynamic manage⁃ment of reserves.
