【摘要】 研究复杂巷道集成建模问题,目前建模方法缺乏对巷道相交处的建模处理与显示。为了能对复杂巷道相交处进行圆滑处理,并且保证巷道内部的连通性,在对称建模[1]方法的基础上,采用冗余点取中线中点法对简单巷道与复杂巷道进行集成建模,立井与平巷的集成建模分为上立井与平巷、下立井与平巷和通立井与平巷三种情形分别处理。以VC++6.0为开发工具,结合OpenGL开发出三维巷道模型的可视化实验系统,并以银母寺铅锌矿为实例对系统进行测试。结果表明,用冗余点取中线中点法和对立井与平巷的集成分情况处理的方法是可行的,为后续的空间分析和其它计算奠定了基础。更多还原

【Abstract】 Study integrated modeling method of the complicated tunnel.The former modeling method lacks of the modeling and visualization of the intersection.In order to handle the intersection of the complicated tunnel,this paper proposed a symmetric modeling[1] based method which takes mid-point of the central line as the redundancy point for integrating simple and complex tunnel,and the integrating of shaft and horizontal tunnel has been discussed into three cases.By using VC+6.0 development tool,Yinmusi lead zinc ore was taken as actual example for testing the system in combination with three-dimensional tunnel model visual experimental system developed via OpenGL.Result shows that the method of taking mid-point of the central line as redundancy point and the method for integrating shaft and horizontal tunnel are feasible.It lays a solid foundation for the subsequent spatial analysis and other computations.更多还原
