Energy analysis of open-pit coal mining

Journal of Mining Science, 1997
1. The use of energy criteria to establish the mine boundaries corresponds to the role of coal-mining enterprises as subsystems within the energy-production system. The criteria here proposed reflect the level of technology not only within coal mining but also within the power industry and in transportation. It is important that the parameters included

Diversification of open pit coal mining with draglining

Journal of Mining Science, 2014
The article deals with aspects of effectivization of open pit coal mining by expanding the area of application of systems with draglining. It is emphasized that this most productive and least resource-hungry system lacks attention due to exhaustion of favourable conditions of its application.

Sizing Storage Facilities For Open Pit Coal Mines

IIE Transactions, 1985
Abstract This paper develops a general procedure to size storage facilities for open pit coal mines. More particularly, the paper presents (1) deterministic models for estimating working stock requirements, and (2) simulation models in the SLAM language which can be used to analyze safety stock requirements.

Digital Transformation of Open-Pit Coal Mining in Russia

2021
The main goal of this paper is to throw the light upon new possibilities of the contemporary digitalization age for the coal mining industry, as well as to identify its advantages for the Russian coal industry. Taking into account the permanent trend of coal demand weakening and declining of carbon intensity of energy consumption over the last years ...

The Coal Mining Model Under Slippery Slope in Yiminhe Open Pit Coal Mines

Geotechnical and Geological Engineering, 2019
To study the unloading of in situ rock stress in coalmining process, mechanics analysis has been carried out, according to which, a stress unloading arch tends to come into being where the slopes are of short strike length. Due to the differences existing between the reserved supporting body and the backfill supporting body, the combined arch walls are
