中文摘要：

五龙沟金矿3 555m以上中段已回采完毕,采用空场法形成了较大的采空区,部分离地表靠近的空区与地表塌陷,给安全生产、地压管理带来负面影响。结合五龙沟金矿现有的设备、以及技术力量对采空区进行处理。通过利用设备三维激光扫描仪对采空区基本情况扫描,最终快速地形成高精度的采空区模型。利用采空区三维模型并采用崩落法和封闭法处理采空区,有效地提高了矿山地质环境的综合治理,并遏止了采空区对后续安全回采矿体的影响。

英文摘要：

The gold mine named Wulonggou has been completed to 3 555 m,a larger area of goaf has been formed since using open-stope method,then part of the goaf result in surface collapsing,which has severely disrupted to the safety of production and the management of ground pressure.This paper presents a solution to the goaf treatment combined with the existing equipment and technical force of Wulonggou Gold Mine.Through the use of threedimensional laser scanner equipment on the goaf,a high precision goaf model has been formed rapidly.It is effective to improve the comprehensive treatment of mine on geological environment by using the three-dimensional model of goaf and the method of caving and closing method,and to curb the influence of goaf on the subsequent mining of ore as well.
