Mathematical Modeling and Measurement of Electric Fields of Electrode-Based Through-the-Earth (TTE) Communication6/1/2017A study using a mathematical model of subsurface electric fields and a prototype electrode-based TTE system to characterize the factors that will affect electric field distribution.
5/1/2017 - Peer reviewed journal articlesAn article that discusses how wall roughness affects radio propagation in tunnels, and presents a unified ray tracing and modal method for modeling radio propagation in tunnels with rough walls.
OMSHR topic page on spontaneous combustion.
3/31/2017 - Research projectsA project to understand the dust generation and transport processes and propose ventilation designs to minimize the dust at mineral processing plants using CFD models.
Identification of Potential Roof Problems Using LED Lighting & Numerical Modeling of Highwall Stability Using FLAC3D3/15/2017 - Contracts and cooperative agreementsA capacity-building contract to (1) develop light technology to identify roof problems and (2) use FLAC3D to model highwall stability and determine the effects of ground vibrations from blasting.
Development of Strength Criteria for Coal and Nonsedimentary Rock Masses and Investigation of Underground and Open Pit Mine Stability of Such Rock Masses3/13/2017 - Contracts and cooperative agreementsA capacity-building contract to develop strength criteria for coal and non-sedimentary rock masses and to investigate the underground and open pit mine stability of these rock masses.
1/1/2017 - Peer reviewed journal articlesAn article that proposes two physics-based, deterministic ultra-wideband (UWB) channel models for characterizing wireless channels in mining/tunnel environments — one in the time domain and the other in the frequency domain.
12/1/2016 - Peer reviewed journal articlesIn this article by NIOSH, researchers collected and analyzed motion capture data and calculated body joint angles in order to enhance intelligent proximity detection systems used with continuous mining machines.
11/1/2016 - Peer reviewed journal articlesThis article from NIOSH describes the methodology used to develop the computational fluid dynamics models, to calculate the model input and to validate the models based on the experimental data.
10/22/2016 - Research projectsA research project designed to determine optimal use of virtual reality (VR) technologies for training and assessing mine emergency responders.
