Current research into mining health and safety was discussed. The status of the mining research program in the United States (US) was summarized. The mining health and safety program of the US Bureau of Mines (USBM), which was dissolved in 1995, was taken over by NIOSH. Research was being conducted at two former USBM research facilities: Pittsburgh, Pennsylvania and Spokane, Washington. The research and development programs of the Pittsburgh and Spokane facilities were expected to see an increased emphasis placed on health related issues, with 35 to 40% of the available funds directed to this field versus 20 to 25% in the past. Research activities in progress at the Pittsburgh and Spokane facilities were discussed. These included developing techniques for reducing exposures to silica (14808607) dust and mine machinery noise, reducing the number of haulage accidents, and improving ground control to reduce groundfall accidents. Other health and safety issues under investigation were discussed. These included investigating health and safety problems associated with automation, examining the role of humans in mining accidents, detecting mine fires early, new strategies for extinguishing mine fires, preventing and detecting hazardous accumulations of combustible materials, and life support during rescue operations in mining emergencies. Research and development activities specific to coal mining were described. These included remote control systems for extended cut mining, a systems approach for longwall mining, and augur and highwall mining systems.
