Integration of Sensing Technologies for Post-Event Monitoring of Hazardous Conditions in the Mining Environment11/22/2016 - Contracts and cooperative agreementsA contract to provide detection of ambient conditions in lesser traversed, remote areas of a mine by way of a repeater system with sensing modules capable of linking into the existing, hardened communications and tracking system.
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.
5/1/2016 - Peer reviewed journal articlesA study that describes the computer modeling of how carbon monoxide moves through an underground mine ventilation network during a fire event.
