“…Draglines are usually used for stripping overburden in an open-pit, which can be directly disposed of in an inner dump (Kyle and Costello 2006;Tuncay and Demirel 2017;Panishev and Kaimonov 2018). Compared with the shoveltruck approach, dragline stripping is a typical combined system that reduces production costs caused by loading and transportation (Sun et al 2019).…”

The reliability factors of a dragline stripping system were analyzed using system reliability theory to improve its reliability and ensure the stability of surface coal mine production. The relationship between the dragline scheduled stripping volume with both the weighted average thickness of the coal seam and the height of the blast casting bench was derived. The results show that the reliability of the dragline stripping system decreases with the weighted average thickness of the coal seam and increases with a reduced casting blast bench height and monthly raw coal production capacity. Furthermore, the dynamic monthly advance distance of the dragline stripping system was found, a new concept of the dragline stripping system reliability and measurement methodology were proposed, and a prediction model for the dragline production capacity was established using a generalized regression neural network. In addition, the steps and processes of the reliability were improved. The study on the Heidaigou surface mine shows that the height of the casting blast bench should be reduced to 10.5 m when its raw coal production capacity is improved from 20 to 30 Mt/a. During the normal production of surface coal, the system reliability can be improved by dynamically determining the weighted average coal seam thickness, accurately predicting the dragline production capacity, and taking other corresponding measures.

The paper presents the review of geoeconomy and geotechnology of efficient solid mineral mining in the north and north-east of Russia. These areas feature harsh climate, predominant permafrost, vast areas of underdeveloped infrastructure and low population density, remoteness from processing and utilization hubs of produced minerals, high cost of goods and services, deficiency of skilled personnel, etc. The adverse and beneficial effects of the interior and exterior environment exert the direct and indirect influence on selection and adaptation of the existing and novel eco-friendly and efficient mining technologies, method and equipment to deposits in the permafrost regions. The authors describe some recent research findings of the Chersky Institute of Mining of the North, namely: integrated subsoil management in the permafrost region; thermophysics and geomechanics of permafrost rocks with regard to anthropogenic factors.
