12/1/2017 - Peer reviewed journal articlesAn article presenting the results of a feasibility study on Industrial Internet of Things (IIoT) applications in underground coal mines based on existing communication and tracking infrastructure.
Simulation and Measurement of Through-the-Earth, Extremely Low-Frequency Signals Using Copper-Clad Steel Ground Rods9/1/2017 - Peer reviewed journal articlesA paper presenting the simulation and measurement results of recent NIOSH research aimed at investigating current injection at extremely low-frequency, and in particular, ground contact impedance.
3/13/2017 - Research projectsA project to enhance the understanding of underground mining communication and tracking system performance through the development and validation of radio signal propagation models.
12/17/2016 - Research projectsA project to investigate the feasibility potential to develop and implement IIoT concepts into the mining industry.
A contract to test the efficacy of deploying a vehicular satellite communication system, augmented with rapidly deployable mesh networking nodes and other emerging telecommunications technologies, during mine rescue and other emergency events.
A contract to ensure that the limited useful spectrum is used efficiently, health and safety hazards are not introduced, and new systems do not interfere with each other or with older systems already in place.
A contract to modify medium frequency radio systems to improve refuge chamber situational awareness in an underground coal mine.
A contract to develop and demo a two-way, through-the-earth communication system for mines that applies state-of-the-art communications technologies to overcome subterranean wireless communication challenges while meeting industrial safety standards.
A contract to enhance key features of the through-the-earth prototype previously developed to improve its usability, investigate design changes to comply with mine safety standards, ruggedize the hardware, and demonstrate performance at coal mine sites.
A contract to develop and test a Media Converter Device (MCD) that allows wireless handheld radios to communicate with leaky feeder communication systems. This will greatly improve voice quality and underground communications coverage in cross-cuts.
