Underground Mine Communications: A Survey
IEEE Communications Surveys and Tutorials, 2009After a recent series of unfortunate underground mining disasters, the vital importance of communications for underground mining is underlined one more time. Establishing reliable communication is a very difficult task for underground mining due to the extreme environmental conditions.

Diesel aerosols in an underground coal mine
Mining, Metallurgy & Exploration, 2021The case study was conducted in an underground coal mine to characterize submicron aerosols at a continuous miner (CM) section, assess the concentrations of diesel aerosols at the longwall (LW) section, and assess the exposures of selected occupations to elemental carbon (EC) and total carbon (TC). The results show that aerosols at the CM sections were

Optimisation in Underground Mining
2007Efficient methods to model and optimise the design of open pit mines have been known for many years. Although the underground mine design problem is conceptually more difficult it has a similar potential for optimisation. Recent research demonstrates some useful progress in this topic. Here we provide an overview of some of this research.

Radon in Brazilian underground mines
Journal of Radiological Protection, 2018Abstract Radon is a chemically inert noble radioactive gas found in several radioactive decay chains. In underground mines, especially those that contain or have contained ores associated with uranium-bearing minerals, workers might be exposed to high levels of radon and its decay products (RDP).

Scheduling in the Context of Underground Mining
2011During the last five decades, numerous publications1 have appeared concerned with the application of optimization methods in the mining industry. Most of them focus on long-term production scheduling for underground mining, e.g. [7] as well as open pit mining, cf. [4].

Underground mine communications
Proceedings of the IEEE, 1978Underground mines are typically extensive labyrinths that employ many people working over an area of many square miles; extensive analysis of mine-communications systems has identified specific problem areas, in particular the excessive times required to locate key personnel underground, the inadequacy of existing phone systems in terms of capacity and
