An explosion caused by molten iron coming in contact with water or wet material.
Industry:Mining
An explosion in the workings or roadways of a colliery as a result of the ignition of combustible gases or coal dust or a mixture of both.
Industry:Mining
An explosion which consists of a sudden pressure rise caused by the very rapid combustion of airborne dust. Ignition of suspensions of combustible dusts can occur in the following ways: (1) initiation by flame or spark, (2) propagation by a gas explosion or blasting, and (3) spontaneous combustion. Little is known about the last-named mechanism, which is relatively rare in mines. The most frequent causes of major coal mine explosions in the United States today are electric arcs, open flames, and explosives.
Industry:Mining
An explosion-proof entrance for conductors through the wall of an explosion-proof enclosure, to provide compressed packing completely surrounding the wire or cable, for not less than 1/2 in (1.27 cm) measured along the length of the cable.
Industry:Mining
An explosive based on two ingredients, such as nitromethane and ammonium nitrate, which are shipped and stored separately and mixed at the blast site to form an explosive mixture.
Industry:Mining
An explosive breaking of coal or rock in a mine due to pressure. In coal mines bursts may or may not be accompanied by a copious discharge of methane, carbon dioxide, or coal dust.
