Abstract

212,896. Krantz, A. March 14, 1923, [Convention date]. Fire-extinguishing by pulverulent and granular materials; fires and explosions, preventing and minimizing in mines.-Apparatus for localizing and quenching explosions in mines comprises a box a which is filled with rock dust, has a loose bottqrn b and is mounted on rollers c on rails above a drift. The shock of an explosion causes the box to move on the rollers so that an end of the loose bottom is released and the dust allowed to fall into the drift.
