The fume escaping from lead furnaces and containing both volatilized and mechanically suspended metalliferous compounds.
Industry:Mining
The function of the neoprene plug is to provide a completely waterproof seal at the open end of the detonator. Moisture penetration could cause desensitization of the explosive charge in the detonator, and in the case of copper-tubed detonators, moisture could produce a potentially dangerous chemical reaction between the lead azide and the copper.
Industry:Mining
The furnace hole, about 1.5 to 2 m above the iron notch and 1 m below the tuyeres, through which slag is flushed two to three times between casts.
Industry:Mining
The furnace in which metal ingots, billets, blooms, etc., are heated to bring them to the temperature required for hot-working.
Industry:Mining
The furthermost end or part of an adit from its beginning or the very place where the miners are working underground toward the mine.
Industry:Mining
The gamma (Gamma ), which equals 10<sub>-5</sub>Oe (7.9577 X 10<sub>-4</sub>A/m).
Industry:Mining
The gangway, entry, or tunnel through which loaded or empty mine cars are hauled by animal or mechanical power.
Industry:Mining
The gap is the greatest distance at which, under certain given conditions, a priming cartridge is capable of initiating a receiving cartridge (receptor). The same explosive is usually used both as primer and receptor, although the gap distance in such a case will also be affected by any change in strength that may occur in the explosive. The gap test can be carried out with the cartridges unconfined or confined, for example, in tubes, in air, or in water. The test gives, for example, information about changes in the explosive due to aging, moisture, temperature, etc.
Industry:Mining
The gases from the calcination of copper sulfide ore. The gases contain sulfur dioxide, SO<sub>2</sub>.
