摘　　要：为了对前期工作中所选择拉沟位置进行合理性验证,根据历史勘探数据与补充勘探数据的整合情况及实测地形、更新后的剥采比等值线,通过地质模型,研究了不同方案的基建工程量及生产剥采比;通过对方案逐步进行优化,最终推演出了基建工程量与生产剥采比均较小的拉沟方案,确保了矿建工程拉沟位置选择的合理性及经济性。In order to verify the rationality of the box cut location selected in the previous work, according to the integration of historical exploration data and supplementary exploration data, the measured topography, and the updated stripping ratio contour,the article studies the capital construction amount and production stripping ratio of different schemes by the geological model. The scheme with less capital construction amount and small production stripping ratio is put forward, which ensures the rationality and economy of the choice of box cut location in the mine construction.
