摘要
针对非层状矿体三维建模的复杂性,讨论了非层状矿体三维建模中有关矿体表面和矿体块段建模基本算法.讨论了实体法建模中平行轮廓线建立非层状矿体表面模型的算法,并把该算法推广到了非平行轮廓线建模,针对利用轮廓线建立实体表面模型的问题,提出利用平面和剖面交叉的方法来产生控制线,以对矿体形态进行控制,进而利用连接轮廓线的方法来进行矿体表面建模.同时,阐述了利用三维普通克立格插值方法建立矿体内部块段模型的关键算法.最后利用VC++和OpenGL作为开发语言,从底层开发了三维非层状矿体建模的三维可视化软件,在某矿山得到了验证,对非层状矿山的实际生产起到了一定的指导作用.图5,参8.
Th e three-dimensional modeling of orebody was an important and difficult issue in the geological and mining engineering. The key algorithm of the orebody＇s face modeling and block modeling were discussed, aiming at the complexity of orebody modeling. The key algorithm of solid modeling was extended to the unparallel contour line. The technique of creating the control line brought from the plane and section to assist the modeling of orebody surface was put forward in order to control the shape of orebody. At the same time, the key technique about the block model of inner orebody by means of 3D common kriging was expatiated. Finally, a practical software, 3D orebody modeling system was developed from the bottom, and its apphcations in some mine are validated, which proved to guide the practical production of the mine. 5figs., 8refs.
