Research On Multi-bid-stage Outsourcing Stripping Project Plan Optimization Of Baorixile Open Pit

Open pit of more than a block outsourcing stripping project exits many unreasonable technical and economic problems in the actual process of production,for example,division of stripping blocks and soil blocks,transport system arrangement, goods traffic planning and so on,affect the economic benefits of open pit,solving these problems can prevent equipment blindness in the work, improve equipment efficiency, reduce the transportation cost,achieve the rationality, science,economy,high efficiency of open pit transportation system, achieve the goal of improving economic benefits of open pit.The paper based on the actual situation of Baorixile open pit of more than a block outsourcing stripping as the research object,analyses the main influences of stripping blocks and soil blocks' division, determine the numbers of stripping blocks and soil blocks using the analytic hierarchy process,arrangement of the transportation system network diagram, and then using the method of operational optimization research on debris flow and flow,optimize Baorixile open pit of more than a block outsourcing stripping project.The research results of the paper have been applied in Baorixile open pit, not only achieve good economic benefits, but also achieve good social benefits, provide basis and reference for other open pit of more than a block outsourcing stripping project plan optimization research.
