Abstract: This paper introduces the present situation of application and popularization of the dragline stripping technology in open pit mines in China, discusses the problems existing in the application of dragline stripping technology in Heidaigou open-pit coal mine, and objectively quantified the gap between domestic and foreign countries in optimization design, production organization management, maintenance and repair, information level and other aspects. It is concluded that the main problems at present are: the design of dragline stripping technology is unreasonable, the level of equipment maintenance and management ability are backward compared with foreign countries. According to the comparative analysis of mining conditions in domestic and foreign countries, it is proposed to replace the current full-line mining plan with partition mining plan. The key research directions of dragline stripping technology should be: design of partition mining method, optimization of dragline operation method, optimization of mining procedure method, and operation and maintenance information technology of dragline.
