摘要
《煤田地质勘探报告》中提供的地质勘探剖面图是地质工作的重大成果,是反映煤田产状的重要图件之一。该图件含有煤田地层、断层、陷落柱、水文地质、地表等丰富的地质信息,为煤矿设计及生产提供了基础资料。在智慧化矿山建设中,该图件对于创建煤田的三维地质模型具有同等重要意义。主要研究从“地质剖面图”创建“三维数字化模型”时矿层及断层建模的实现算法。在建模过程中,将二维地质剖面图转换为三维剖面图,手动交互式选择相邻剖面图上的断层或煤岩层分界线,生成断层面和煤岩层三维实体,实现了煤田地质模型的三维重建,为矿井勘察、设计及生产提供了新的煤田地质模型表现手法。
The geological exploration profile provided in the"Coalfield Geological Exploration Report"is a major achievement of geological work and one of the important maps reflecting the occurrence of coalfields.The map contains rich geological information such as coalfield strata,faults,collapse columns,hydrogeology,and surface,providing basic data for coal mine design and production.In the construction of smart mines,this map is equally important for creating a 3D geological model of a coalfield.This paper mainly studies the realization algorithm of mineral seam and fault modeling when creating"three-dimensional digital model"from"geological profile".In the modeling process,the 2D geological profile is first converted into a 3D profile,and the faults or coal-rock layer boundaries on adjacent profiles are manually and interactively selected to generate three-dimensional entities of the fault plane and coal-rock layer,thus realizing the coalfield geological model.The three-dimensional reconstruction of coal field provides a new representation method of coalfield geological model for mine survey,design and production.
