Not only a means of structuring EBVM is elaborated, but also a mathematical model of linear programming is constructed to solving optimization problems. Moreover, steps of Lerchs-Grossmann algorithm are described from the point of view of the set theory. The method has been realized in DIMINE software, and applied to the actual boundary optimization and design of open-pit mines. Results show that the method is able to overcome the shortcomings of traditional manual methods and solve the optimal exploitation scenarios quickly and accurately under different parameters. It provides basis and assurance for mining company with the optimal use of resources., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=UsU8yRhZPkiyeXe5m8fwAw==, pdfFileSize=1517842, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
