Study On Application Dragline Overcastting System To Heidaigou Opencast Coal Mine

This thesis sets forth the application of dragline for the extension of Heidaigou Opencast Coal Mine from the production of 12mt/a to 18mt/a, which is based on analysis of the application of dragline in internal and external mines,studies of the theoretical principle, and integration with the current mining technology of the open cast coal mine. To consider the dragline operation program, optimize the mining parameters, and combine with the existing system,compare the single shovel and trucks system and draglinesystem,to find out the optimum application of dragline system in Heidaigou Opencast Mine. Make a detail-mining plan. What's more, it is expounded that the applixation of dragline is really practical in mining technology and economical in cost.
