摘　　要：为处理某金矿民采采空区的隐患,运用3D激光探测系统对采空区进行探测,结合建模软件Surpac建立三维可视化模型,得到了空区的体积、暴露面积、围岩垮塌等信息。在此基础上,对采空区隐患进行分析,结合矿山实际情况,提出充填-封闭联合治理方案。建立地压监测系统以验证空区治理效果,地压监测数据显示,空区治理后,围岩的位移趋于平稳,应力减小,表明空区的治理取得预期的效果。In order to treat the hidden trouble of mined - out areas formed by illegal mining in a gold mine, the mined - out areas were detected with 3 D Laser detection system. 3 D visual model of mined - out area was established using modeling software Surpae, Such data as the volume and exposed area of the mined - out areas and the collapse of surrounding rock, etc. were determined. Based on these ,the hidden troubles of mined -out areas were analyzed. Combined with the actual conditions of the mine, a combined treatment scheme of filling and closing mined - out area was proposed. A ground pressure monitoring system was established to verify the effect of mined - out area treatment. The data of ground pressure monitoring showed that after treating the mined - out areas the displacement of rock tended to be stable, the rock stress decreased, these indicated that the desired effect of mined - out area treatment has been achieved.
