2/1/2002 - Conference papersMine fires can be especially perilous because toxic products can quickly spread well beyond the fire zone thereby exposing all underground miners to dangerous and deadly conditions. This paper provides a review of the available materials and technology ...

2/1/2002 - Conference papersThis paper examines methods for limiting occupational silica exposures for roof bolting personnel in underground coal mining. It also evaluates a metal rake, a flexible insert, and a rigid insert for cleaning the roof bolter dust collector box.
-
2/1/2002 - Conference papersReport on a NIOSH study to identify factors that may contribute to nitrogen oxides (NOx) production associated with non-ideal detonation of blasting agents.
-
2/1/2002 - Conference papersThis report discusses a cooperative research study performed on a surface drill retrofitted with a new pressurization and filtration system. Respirable dust concentrations were substantially reduced from 0.64 mg/m3 during pre-testing to 0.05 mg/m3 duri...
-
2/1/2002 - Conference papersDiscusses current NIOSH research to improve mine ventilation and mine air quality, particularly for large opening mines.
-
1/1/2002 - Conference papersThis paper examines the development of dust sampling methods in U.S. coal mines, with emphasis on the benefits of personal sampling and on recent developments that permit real-time assessment of dust exposure.
-
12/1/2001 - Conference papersAn automated PC-network-based seismic data acquisition and processing system has been developed by NIOSH for use in mine safety studies. Several systems have been constructed and deployed in the field for testing and application. These systems are now b...

9/1/2001 - Conference papersThis report focuses on two areas of research to lower miners' exposure to respirable dust at surface operations. These areas deal with enclosed cabs methods to lower dust levels at surface drills.
-
9/1/2001 - Conference papersNIOSH has developed a patented active proximity warning system called HASARD (Hazardous Area Signaling and Ranging Device) which employs low-frequency, low-power magnetic fields which are quite impervious to severe environmental conditions.
