根据层状矿床特点,在Surpac采矿软件基础上进行了有针对的二次开发,形成了层状矿床地质模型建立流程,根据不同需要分别建立了面模型、体模型、网格模型,论述了建模过程中的地质构造处理方法和网格模型、顶底板面模型、体模型的建立方法,经在华能伊敏露天煤矿应用,取得了满意的效果。 According to the characteristics of stratiform deposit, the secondary development based on the Surpac mining software has been carried out, and the formation process of the stratiform deposit geological model has been established. According to the different needs, the surface model, the body model and the mesh model have been established respectively. The geologic structure processing method and grid model, roof and floor surface model and body model building method in the mold process have achieved satisfactory results after being applied in the Huimin Yimin open-pit coal mine.
