Research of Model Selection of Dragline Equipment of Opencast Mine

The existing geological conditions of our opencast mines are suitable to adopt overcastting mining technique of dragline.The paper researched model selection of dragline equipment of opencast mine,analyzed determination principle of main mining parameters of model selection of dragline equipment in opencast mine,introduced basic steps of model selection as well as calculation method of main parameters of dragline equipment.At last,it used computer simulation technology to build mathematical model of model selection of dragline equipment.
