Quantifying the coal mining impact on the ecological environment of Gobi open-pit mines
Science of The Total Environment, 2023Xinjiang is a coal-rich region with many bare rocky and gravelly areas with a delicate and fragile ecology. What is the ecological impact of mining activities? In this study, the Salinity Index (SI-T), New Gravel Land Index (NGLI), and Land Deterioration Index (LD) were used to establish an improved remote sensing ecological index (IRSEI) for the ...

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

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.

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.

Simultaneous Optimization of Final Pit and Production Schedule in Open-Pit Coal Mines
Advanced Materials Research, 2011A dynamic sequencing method has been developed that can simultaneously optimize the final pit and the production schedule of an open-pit coal mine. The method first establishes a geological seam model of a bedded coal deposit which estimates the relevant attributes of coal seams at the center of each block on the X-Y plane.
