摘　　要：为打破煤矿工业广场建模模式目前存在的高度依赖人工操作的现状,实现数字矿山规模化规范化建设、煤矿地面建筑设备模型量产化。本文对煤矿工业广场生产建筑群进行空间结构分析,着重分析煤矿井口、煤矿车间、煤矿办公楼的几何空间结构及生产设施的空间几何构型元素,提出一种分体分面组合模型自动建模技术。首先,通过将复杂的生产建筑群进行个体解构和几何拆分,将整套地上生产线设备及建筑拆分为最小规则(不规则)几何单元体,构建顶视投影弧段索引拓扑图;其次,通过线性封闭弧段环高程拉伸生成几何体空间组合关系构建建筑群;最后,以灵新煤矿为实验区域进行验证。结果表明:本文方法能够模拟建筑结构与设备的几何独特性,且纹理外观满足数字化要求;总建模工时由原来的每10栋建筑3.25人天降低到0.78人天,产能提升达到预期。In an effort to reduce the heavy reliance on manual operations inherent in the modeling of coal mine industrial squares,this study addresses the limitations posed by traditional modeling methods.These limitations include high dependence on manual processes,lack of reusability,and constraints on productivity.A spatial structure analysis was conducted on the production building complex within the coal mine industrial square,this led to the proposal of a split face combination model automatic modeling technology.By deconstructing and geometrically splitting complex production building clusters,until the buildings are divided into the smallest independent“regular/irregular geometric bodies”that cannot be further subdivided.A building cluster can be divided into multiple buildings,and each building can be split into several geometric unit bodies,with no logical order between them.Then,by constructing a topological diagram of the top view projection arc segment index for geometric unit bodies,spatial relationships are described.all regular geometric unit bodies undergo top view projection,while irregular entities such as roofs and coal storage silos require the definition of special geometric constructors.This two-dimensional mapping surface is divided into a closed line composed of linear arc segment rings with directional attributes.the spatial combination relationship of geometric bodies is generated through elevation stretching of linear closed arc segment rings to construct the building cluster.By constructing regular geometric bodies and geometric constructors for special facilities,all building facilities within the industrial square are assembled in a manner analogous to building blocks.Using Lingxin Coal Mine as the experimental area,the results demonstrated that the geometric uniqueness of the building structures and equipment was accurately simulated and presented,meeting digital requirements for texture appearance.Furthermore,the total modeling time was reduced from 5 person-days per ten buildings to 0.
