    Description of a Large Catastrophic Failure in a Southwestern Wyoming Trona Mine
    Swanson P ;
    Zipf, R. Karl, Jr.
    1999/06/01 | Mining Publications
    A large-scale collapse occurred in a room-and-pillar trona mine in southwestern Wyoming on February 3, 1995. An area measuring approximately 1 by 2 km (2800 by 7200 ft) collapsed abruptly without warning. This paper describes the resulting mine damage, airblast, gas emissions, and seismic event. The collapse is analyzed in terms of a cascading sequ ...

    1999/06/01 | Mining Publications
    Within the last 4 years, seven documented explosions of methane and/or coal dust occurred within sealed areas of underground U.S. coal mines. These explosions, believed to be initiated by lightning strikes on the surface, destroyed numerous seals and caused considerable damage external to the sealed area. Fortunately, these explosions did not cause ...

    A Unique Approach to Determining the Time-Dependent In Situ Strength of Coal Pillars
    Biswas, Kousick ;

    1999/06/01 | Mining Publications
    In general, it cannot be assumed that the strength of coal pillars remains constant over long periods of time. Field observations indicate that a coal seam, especially when it contains a parting layer, deteriorates over time, reducing the load-bearing capacity of the pillars. This paper discusses a unique approach to determining the time-dependent ...
