基于C-ALS实测的复杂采空区充填标高判定

摘要

Filling the goaf is currently the most effective treatment method of goaf disposal, however it is hard to determine the fill-ing volume and elevation of the complicated goaf, because it is difficult to know the space form and volume. Chifeng NFC Baiyinnuoer Mining Co. , Ltd. adopts C-ALS three dimension laser scanning system to detect the complicated goaf. A 3D entity model was estab-lished by Surpac software. The proposed model segmentation method uses a certain elevation plane to cut apart model, so as to make the volume of segmentation model and filling capacity is equal, which can determine the filling elevation required for complicated goaf fast and effectively.%充填采空区是目前最为有效的采空区处理方法，然而复杂采空区空间形态和体积等不易确定，这给确定采空区的充填量及充填标高带来一定困难。在赤峰中色白音诺尔矿业有限公司利用C-ALS三维激光扫描系统，对复杂采空区进行探测，并辅以Surpac软件建立采空区三维实体模型，提出模型分割法，利用一定标高的平面分割模型，使分割的模型体积等于充填量，从而快捷、有效的确定复杂采空区所需的充填高度。
