煤炭三维地质建模信息系统的研制及关键技术

Key technologies and development of a 3D coal geological modeling information system

对煤炭三维地质建模信息系统软件QvCoalMine的研制过程及关键技术进行了分析和说明。对系统的主体构架、业务流程、功能模块进行了介绍,详细分析了该系统在研发过程中的主要关键技术:真实折剖面技术;"钻孔-剖面-等高线"循环动态建模技术;地层煤层一体化建模技术;三维模型的动态编辑与分析技术。利用我国内蒙古东胜煤田的多个煤炭勘查区对本系统进行了综合测试和运用,结果表明:QvCoalMine系统提供的三维建模功能,能高效地构建出煤炭地质领域大多数地质对象和勘探开采工程的三维模型。

Analyzed and explained the development and the associated key technologies of a coal geo-science modeling information system,QvCoalMine.Firstly the mainframe,workflow and function organization of this system were separately introduced in detail.Then several key technologies used in QvCoalMine system were analyzed mainly in the following points：① the true zigzag sections,② borehole-section-contour-based dynamical modeling,③ the consistent coal-stratum modeling,and④ dynamical edit and analysis on the resulting models.As a result,from the practical applications on several exploration areas in Dongsheng coalfield,QvCoalMine can construct a series of 3D models for most of the coal-seams and the associated geological bodies and geological engineering efficiently.
