| 摘 要： | 五龙沟矿区3555m平硐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造成地表塌陷,为避免冲击地压隐患以及对后续正常开采产生不必要的麻烦,现对已形成的采空区和塌陷区域进行处理。利用采空区三维激光扫描仪对采空区基本情况进行扫描,对形成的采空区研究处理。三维激光扫描技术获取数据的快速性、高效性、高精度和高分辨率特性是传统测量方法无法比拟的,该技术的应用有着广泛的前景。通过对采空区的安全性能、对后续采矿作业的影响、经济效益以及地表实际现状的探讨,最终决定采用崩落法和封闭法处理采空区。

| Abstract: | The gold mine named Wulonggou has been completed to 3555m, a larger area of goaf has been formed since the use of open-stope method, than part of the goaf gave rise to 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 three-dimensional 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. |
