摘　　要：勘探剖面是矿山设计、生产过程中的基础性成果图件,在矿山三维建模中发挥着重要作用,其中勘探剖面从二维坐标系向三维坐标系的转换及其误差分析、校正是矿山三维建模的一个重要环节。针对当前人工或交互式勘探剖面坐标系转换过程存在费时费力、易出错等问题,在基于基准点的勘探剖面坐标系转换原理的基础上,首先探讨了基于地质体断面面积标准差的转换误差评价方法;然后,提出了基于转换域的勘探剖面坐标系转换的新方法,详细叙述了算法的计算步骤,并分析了算法的复杂度;最后,以湖南省某金属矿山为例,对比分析了勘探剖面坐标系转换的质量,并验证了所提方法的可行性。As the important achievements in the mine designing and producing processes, the exploratory profiles are very significant for modeling the three-dimensional mine. The transformation of the profiles from 2D to 3D coordination systems, and the evaluation and emendation of transformed errors are important. For reasons of complicated work of traditional transformation, this paper promotes a new method to transform the coordination of the profiles. Based on the standard deviation of section area of the geological entities, an evaluation of the transformed error is put forward. Then, the method to assess the error is investigated, and a transforming-domain based algorithm to transform the coordination of the profiles is proposed, the algorithm and its complication are depicted in detail. Finally, a practical example which uses the profiles of a metal mine in Hunan Province shows that the method proposed in this paper is feasible, and the transforming result is better than that based on the single benchmark.
