Diversification of open pit coal mining with draglining
Journal of Mining Science, 2014The 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.

Energy analysis of open-pit coal mining
Journal of Mining Science, 19971. 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

The Coal Mining Model Under Slippery Slope in Yiminhe Open Pit Coal Mines
Geotechnical and Geological Engineering, 2019To 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

Monitoring and control airblast overpressures in an open pit coal mine
Physics and Chemistry of the Earth, Parts A/B/C, 2021Abstract Besides ground vibrations, air transmitted vibrations or airblast overpressures (AOp), are also generated during blasting operations. Mae Moh coal mine, Thailand, has been concerned about both ground and air vibrations because the residents nearby are located less than 2 km to the southeast of the mine.

Sizing Storage Facilities For Open Pit Coal Mines
IIE Transactions, 1985Abstract 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.

Replacement Study of Off-Highway Trucks in an Open-Pit Coal Mine in Turkey
Mineral Resources Engineering, 2000The proper assignment of equipment can be achieved by insuring a timely investment and a timely replacement policy through the mine life. Mine design engineers must constantly decide whether existing assets should be continued in service or whether available new assets will better and more economically meet current and future needs. These decision must

Buckling failure at an open-pit coal mine
1996A very complex failure took place at an open-pit coal mine in the eastern Turkey. The floor of the open-pit heaved up as a result of the buckling failure of the coal seam and a combined form of shear and sliding failure of slope benches occurcd. The investigations showed that a weak clay band within the coal seam was the main cause of the failure.
