7/19/2016 - Contracts and cooperative agreementsA contract to design the integration of appropriate Mine Escape Vehicle (MEV) technology into either an existing mantrip being refurbished or a new mantrip under construction.
Method for Improving Ventilation & Gas Monitoring with an Advanced Fiber Optic Based Mine-Wide Monitoring System7/19/2016 - Contracts and cooperative agreementsA contract to create an advanced mine-wide distributed monitoring system utilizing a low power intrinsically safe fiber optic backbone for improving ventilation and gas and temperature monitoring in underground mines.
7/16/2016 - Contracts and cooperative agreementsA contract to evaluate the practicality and permissibility of modern laser-based technology for remotely detecting and mapping potentially explosive methane accumulations.
7/1/2015This publication of conference proceedings discusses a recently developed series of models by NIOSH utilizing Computational Fluid Dynamics (CFD) to study gas distribution around a continuous mining machine.
9/17/2012 - Contracts and cooperative agreementsA contract to integrate a micro electro mechanical system (MEMS) component into specialized electronics to measure methane levels in underground coal mines.
6/1/2010 - Conference papersA multi-gas simulated gas monitor system (GMS) is a wireless simulation tool. It is designed to assist mine rescue team members learn about gas detection, gas concentrations, and encourage subsequent decision-making actions by team members.
11/1/2008 - Conference papersThis work by NIOSH has modelled the impacts of borehole pattern and design and the effects of increasing face length on gob gas venthole performance.
6/1/2008 - Conference papersThis paper describes research conducted to compare the performance, including response time and accuracy, of selected instruments using infrared and catalytic sensors.
12/1/2005 - Information CircularsThe purpose of this study was to compare calibration gas cylinders having balance gases of nitrogen or air that are commonly used to calibrate portable NO2 gas monitors. Because even low concentrations of NO2 can have an extremely adverse effect on ind...
1/1/2005 - Conference papersThis paper describes test procedures used to evaluate performance of methane monitors that could be used underground for continuous personal monitoring of methane. The information in this report provides data that allow the reader to make side-by side c...
