  • THE WILBERG MINE FIRE

    T he Wilberg Mine fire, which claimed the lives of twenty-seven miners on 19 December 1984, was the most deadly coal-mine fire in Utah history and the worst U. S. mine disaster in a dozen years. Investigation of the fire revealed serious failures by the agencies charged with assuring coal mine safety. Located in Emery County, some 115 miles southeast of Salt Lake City, the Wilberg Mine was one

  • Squib (explosive)

    History. Squibs were originally made from parchment tubes, or the shaft of a feather, and filled with fine black powder.They were then sealed at the ends with wax. They were sometimes used to ignite the main propellant charge in a cannon.. Squibs were once used in coal mining to break coal away from rock.In the 1870s, some versions of the device were patented and mass-produced as Miners

  • Development of Environmental Friendly Dust Suppressant

    Therefore, the dust suppression effect of SDS-SPI cementing dust suppressant solution is more pronounced. As for the dust suppressant solution used in coal mines, considering the economic cost and the dust suppression effect, it would be non-ideal to have an excessively high viscosity. Usually the range of viscosity lies between 12.0–20.0 mPas.
