In the USA, the National Institute for Occupational Safety and Health (NIOSH) does a lot of work and has provided news of interesting new developments. The Coal Dust Explosibility Meter (CDEM), a hand-held instrument developed by NIOSH uses optical reflectance to measure the explosibility of a rock dust and coal dust mixture. The CDEM is now commercially available. Also, the use of infrared sensors for monitoring methane underground is examined and a series of tests performed to evaluate the feasibility of infrared instruments for underground use is described.
