Study on optimization selection of mining scheme in open-pit mine based on AHP-TOPSIS model
Taking Shengli East No.2 Open-pit Coal Mine as an example,based on the comprehensive analysis of the geological conditions,mining status and medium and long-term planning,this article determines three mining schemes with different working line lengths and advancing modes of the open-pit coal mine.The stripping ratio,internal dumping space,haul distance,infrastructure volume,secondary stripping volume and mining difficulty of the corresponding open-pit coal mine are different,and each has its own advantages and disadvantages.The article presents a combination of Analytic Hierarchy Process(AHP)and TOPSIS method to select the optimal mining plan and avoid subjective factors affecting the decision-making results,uses the AHP method to construct an Analytic Hierarchy Process(AHP)structural model for the selected 9 important indicators and calculate the weight values of each indicator.The TOPSIS comprehensive evaluation method calculates the closeness between each plan and the positive and negative ideal solutions,and ultimately determines the"600 meter north expansion plan of the zoning boundary"as the optimal mining plan.
