Dumping Scheme Research Of Yilan Open Pit Mine

Because of the production of Yilan open pit mine was unreasonable in the past time, so there are a series of production problems badly need a properly later production plan to guide the production for the future.After of the careful study of Yilan open pit mine geological data, based on the sorting and analysis of the drilling data and stope status figure, use the CAD secondary development modeling technology to build sandstone, shale, upper coal, middle coal, lower coal entity model of Yilan open pit mine and the present situation of open pit mine stope DTM surface model. According to the requirements of the production scale, reasonable economic stripping ratio, the mine production capacity and a series of design requirements of mine production standards formulate mine mining plan,and draw the engineering position plan at the end of each year. On the basis of the above designs, build reasonable model of in dumping and external dumping, including the determination of the amount and the location of the in dumping and the external dumping etc. Input different mine road attribute node in road transportation optimization software prepared by VB, drawing open-pit transportation network, and doing the optimal planning for material. Eventually set a reasonable pan for Yilan open pit mine.
