10/22/2016 - Research projectsA project to reduce exposures of underground miners to diesel particulate matter and gases through implementation of control technologies and understanding of the risks associated with exposure to diesel engine emissions.
7/19/2016 - Contracts and cooperative agreementsA contract to simulate the development and evolution of natural gas (NG) explosions in mine tunnels.
Development of a Method for the Remote Characterization of Underground Mine Ventilation Control by Multiple Tracer GasesA capacity-building contract to develop a method to remotely characterize underground mine ventilation control by multiple tracer gases.
7/18/2016 - Interagency agreementsAn interagency agreement to develop cryogenic breathing apparatus and supply/filling systems for mine escape, rescue, and refuge.
A contract to develop a liquid crystal (LC)-based nitrogen dioxide monitor housing a sensor which will detect and trigger an audio-visual alarm to warn miners when the concentration of nitrogen dioxide levels exceeds the threshold limits.
A contract to extend communication and hazard monitoring into bleeders or other remote workings in an active underground coal mine.
7/16/2016 - Contracts and cooperative agreementsA contract to assess four types of existing technology that can be applied to seals in a nondestructive manner under experimental conditions, including radio frequency sensing, ultrasonic sensing, ground penetrating radar, and tracer gas methods.
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.
5/23/2016 - Contracts and cooperative agreementsA contract to design composite sensing materials to develop a sensor that is sensitive to carbon monoxide and nitrogen dioxide at the desired concentrations but is not affected by the interferences present in mines.
Effects of Hydrotreated Vegetable Oil on Emissions of Aerosols and Gases from Light-Duty and Medium-Duty Older Technology Engines4/1/2016 - Peer reviewed journal articlesThis article by NIOSH describes a study conducted to assess the potential of hydrotreated vegetable oil renewable diesel (HVORD) as a control strategy to reduce exposure of workers to diesel aerosols and gases.
