摘　　要：针对某露天矿的复杂隐伏空区,运用三维激光扫描和无人机扫描两种精准探测装备对空区进行了精准探测,准确测定了空区的空间形态和位置。结合现场工程钻探结果,分析了空区的成因,采用悬臂拉裂式崩塌模型,选取了对地比压较大的1190E钻机和D11T推土机为例,计算出两种设备的安全作业距离,为该露天矿的塌陷坑治理提供了基础依据。Aiming at the complex hidden goaf of an open-pit mine,two kinds of precision detection equipment,including threedimensional laser scanning and unmanned aerial vehicle scanning,were used to accurately detect the goaf,and the spatial form and position of the goaf were accurately determined.Based on the results of field engineering drilling,the causes of the goaf were analyzed,and the cantilever cracking collapse model was adopted.The 1190Edrilling rig and D11Tbulldozer with large specific pressure to the ground were selected as examples to calculate their safety distances,which can provide the basis for the treatment of the collapse pit in the open-pit mine.
