摘　　要：运用三维激光扫描仪对某矿山地下采空区进行探测,获得采空区的实际位置以及尺寸、形状等一系列数据,将数据导入Surpac软件中创建模型,再将其耦合至FLAC^(3D)中进行稳定性分析,分析结果表明:采空区顶板与侧帮围岩位移较小,上盘围岩失去支撑后,顶板受压,但顶板与侧帮围岩均未破坏,采空区相对稳定。与传统的方法相比,该方法明显提高了分析的准确性与真实性,为矿山的安全生产与采空区充填提供了科学依据。Detection was made of the underground mined-out area in a mine using 3D laser scanner to get its actual position, size, shape and other data. The stability analysis of mined-out area was conducted by building a model with input of the data in Surpac software and coupling of the data in FLAC^3D. The analysis results show slight displacement of surrounding rock on the lateral wall and roof in compression without support of surrounding rock on the hanging wall, but no failure of roof and surrounding rock on the lateral wall and relative stability of the mined-out area. Compared with the conventional method , this method significantly improved accuracy and authenticity of the analysis, providing a scientific basis for safety production and filling in mined out area in mines.
