ABSTRACT
The open cast method by use of dragline stripping is an advanced mining technology which combines excavation, haulage and dumping into one operation to move the overburden into the mined-out area. Since 1970s, dragline strip mining method has obtained rapid development and worldwide applications. Some new technique developed for dragline stripping in recent years is introduced. There are a number of newly-developed surface coal mines in China, most of them possess favorable conditions for huge dragline stripping application, e.g. large in mining area; abundant in coal resources; horizontal buried deposit. Among them HDG surface mine has commenced on reform and extension engineering for dragline strip mining. As a case study, the dragline selection, coal haulage system and cast blasting technique for HDG surface mine are introduced.
