This paper highlights recent developments by the U.S. Bureau of Mines for the prevention of fires and explosions in underground coal mines. The areas addressed include (1) instruments to remotely monitor methane and coal dust accumulations, (2) cutting bits with back-mounted water sprays to prevent frictional gas ignitions, (3) new ways to distribute passive water tub barriers along the ribs to suppress coal dust explosions and "explosion-powered" triggered barriers that utilize a solar panel as a detector, (4) a sensitive smoke sensor for the detection of incipient fires in the presence of diesel exhaust, (5) an improved laboratory-scale test method for fire-resistant conveyor belting, and (6) inflatable seals to isolate fire areas.
