Accurate prediction of dynamic mining subsidence is a critical factor in mitigating the disturbance of surface structures due to underground mining and therefore paramount for …

Related work includes the data-driven mine-to-mill framework proposed and tested in [19,20]. It was concluded that material tracking needs to be performed in a more com-prehensive way to better connect mining and mineral processing data, as well as stockpile management, and the required infrastructure was found to be the main limitation for imple-

Experimental apparatus. In the field of coal mining, the similar material model is an effective method with which to study the failure phenomenon of a rock mass because of coal mining (Dai et al. 2010; He et al. 1991; Industry 2004; Ren et al. 2010; Wu et al. 2002, 1998; Yuan and Wu 2003; Zhou et al. 2014b).The geological and mining conditions in the coal mine …

Mining is essentially the movement of material to separate valuable minerals from those that are not; the first stage of separation occurs at the mine, the second at the …

Material movement is a foundation process in copper mining. As copper demand continues rising, especially due to expanding renewable energy and zero emission systems, material volumes moved at copper mining sites are …

In order to obtain the particle movement trajectory clearly, the mining pits of the mining area was chosen as simulation background. The mining pits area were modelled into a mining pit flow field model, which was established by x-direction length of 2627 m, Y-direction length of 1828 m, and the vertical height of z-direction of 1500 m.

In this study, a two-dimensional numerical model, established by the discrete element method code PFC2D, was adopted to investigate the mechanical mechanism of …

The aim of this study is to obtain movement laws of overlying strata above a fully mechanized coal mining face backfilled with gangue and solve the problem of surface subsidence during coal mining ...

We chose a threatened population of grizzly bears (Ursus arctos) in Alberta, Canada 22 to study the effects of open-pit mining on the movement ecology of these animals in a landscape with large-scale coal mining operations. While surface mining for coal is not as widely publicized as the "world-renowned" Alberta oil sands exploitation, coal ...

The compressive deformation of backfill materials is large due to the large mining depth of coal seams and high mining-induced stress during the deep backfill mining. Therefore, the controlling effect on strata movement significantly differs from that in shallow coal seams. The research aims to explore the influences of the compressive deformation of backfill materials on …

This research study examines the impact of shifts and lunch breaks on mining operations, particularly focusing on delays in hauling equipment used to supply extracted material to crushers. These delays significantly reduce productivity, averaging below 80% during regular working hours and adversely affecting mine profitability. To address this issue, a Q-learning …

Landslides caused by underground mining are very common in mountain mining areas, and thus threaten human lives and assets. Under the superposed influence of underground mining and landslides, surface movement in mountain areas is different from that in flat areas. Further understanding of the law of surface movement in mountain mining areas can protect …
