Paper Title:
Equipment Selection Optimization System of Draglines and it’s Applications in Opencast Coalmine in China
  Abstract

Draglines equipment selection optimization involves many factors. Manual simulation has many shortcomings,such as lower calculation accuracy, less programs, long design cycle, so it is hard to make a optimization program. Equipment Selection Optimization System of Draglines (ESOSD) is designed and developed according to the deposit occurrence of opencast coalmines in China. Visual Basic 6.0 is used as programming language, Access 2003 as Background database and the software such as Microsoft Excel 2003 and Autodesk AutoCAD 2004 are integrated in the ESOSD. Three mining schemes of SL opencast coalmine that put forward by SY Design and Research Institute were optimized by using ESOSD. The results show that scheme Ⅱ is better than the other two schemes, which is recommended as the draglines stripping scheme. The main parameters of scheme Ⅱ are as follows: stripping bench height is 45 meters; stripping bench width is 60 meters; throwing blast is adopted; stripping bench is 16 meters lowered by two D10R580HP dozers; dragline model is 1570WS, which boom length is 91.7 meters and bucket capacity is 72.7 cubic meters, and annual overburden amount is 17.2 Million cubic meters. By comprehensive comparison the optimization results with that of SY Design and Research Institute, The total cost reduces 7.512 Million Yuan (RMB) than that of the institute, bucket capacity of dragline reduces 10.7 cubic meters, and boom length reduces 14.3 meters. The optimization results show that ESOSD is reliable and practical, and it can be used as a decision support system for draglines equipment selection optimization.
