摘　　要：空区群三维建模是矿山高效处理隐患空区并回收残矿的基本保证,因此提出一种快速的、非三维激光扫描的方式对复杂空区群进行三维概略建模。基于Auto-CAD与3DMine软件,提取矿山二维图纸的高程测点并作严格空区分区,逐一快速建立单空区实体模型,最终生成整个复杂空区群三维实体概略模型。一方面该方法建模过程经济高效,可清楚直观地展现整个矿山空区群的空间拓扑关系,另一方面概略模型可与扫描精准模型协同参与矿山开采规划设计,并在矿山建模实例中已取得良好的印证。The three-dimensional modeling of goaf group is the basic guarantee for mines to efficiently process the hidden danger zone and recover the residual ore. Therefore, a fast, non-three-dimensional laser scanning method is proposed to build three-dimensional sketchy model for the complicated goal group. Based on Auto-CAD and 3DMine software, the elevation measurement points of the mine＇s two-dimensional drawings are extracted and used for strictly goal division, and quickly establishing single goal solid models one by one; finally generating a three- dimensional solid sketchy model of the entire complicated goal group. On one hand, the modeling process is cost- effective and the model can demonstrate the spatial topological relationship of the entire mine goaf group clearly and intuitively. On the other hand, the sketchy model can participate in the mining planning design in cooperation with the scanning precision model, and it has obtained a good confirmation after being used in the mine＇ s modeling examples.
