Short-Term Evaluation of Compressible Stoppings Used in Trona Mines
In an attempt to reduce the damage to ventilation stoppings caused by strata convergence, many mines are now using new stopping construction techniques that include compressible materials. The Bureau of Mines study concentrated on compressible stoppings in use in underground trona mines, all of which had overburden in excess of 1,000 ft. The overburden depth, in conjunction with the relatively soft floor in trona mines, has commonly created excessive floor heave throughout mined-out entries.
