Given a short term mining plan, the task for an operational mine planner is to determine how the equipment in the mine should be used each day. That is, how crushers, loaders and trucks should be used to realise the short term plan. It is important to achieve both grade targets (by blending) and maximise the utilisation (i.e., throughput) of the mine. The resulting problem is a non-linear sched...

The new caving megaprojects that are planned to go into production in the next decade have scheduled horizontal developments at very high rates, which difficult achieve. Research has been conducted seeks model construction times for underground determine feasibility of achieving rates. However, these previous attempts do not consider all operational aspects make up mine development cycle. Here,...

Mining usually causes severe anthropogenic changes by which the groundor surface water might be significantly polluted. One of the main problems in the mining industry are acid mine drainage, the drainage of heavy metals, and the prediction of mine water rebound after mine closure. Therefore, the knowledge about the hydraulic behaviour of the mine water within the flooded mine might significant...

BACKGROUND The use of formative research as a critical component of intervention planning is highly supported in the literature. However, studies that report such processes in practice are minimal. This paper reports on the formative data collection and analysis that informed the development of a multilevel intervention that utilizes mine assessment technology to bridge health communication bet...

Adequate water distribution in mines is crucial for both cooling and production. As deep-level become deeper, the requirements, subsequent dewatering also increase. Numerous studies on mine planning exist; however, these fail to recognise integrated nature of system, which comprises service supply system. These commonly neglect intensity, life-of-mine planning, use zero-waste baselines. In this...

For efficient mine planning and economic assessment, knowledge of subsurface structures ahead of mining in 3D and with high resolution is very useful. Tools such as 3D seismology have been adapted from the oil industry and applied to the planning of ultra-deep mines, but these tools lack the resolution to reveal <20 m features that hazard mine workings (Pretorious et al., 1997). Three-dimension...

The large collection of educational data provides the opportunity to study how students learn and can be a source of valuable knowledge both for students when planning their studies and for educators and administrators for improving their curricula and services. In our work, we mine course relationships and student consumption patterns found in the data. We present a visual analysis system, Lea...

Shifting markets can cause unexpected, stochastic changes in rural landscapes that may take local communities by surprise. Preferential siting of new industrial facilities in poor areas or in areas with few regulatory restrictions can have implications for environmental sustainability, human health, and social justice. This study focuses on frac sand mining-the mining of high-quality silica san...
