In ore dressing, smelting, and refining, a laborer who sprays the inner
surfaces of furnace walls and roof with a slurry of silica, water, and
fireclay to protect brick, using a compressed-air gun. Also called slurry
man; sprayer. DOT
A chimney built over a furnace for increasing the draft. Fay

Having deep grooves or striations.
a. A coal lithotype characterized macroscopically by its silky luster,
fibrous structure, friability, and black color. It occurs in strands or
patches and is soft and dirty where not mineralized. Its characteristic
microlithotype is fusite. CF:vitrain; clarain; durain.
Syn:mineral charcoal; mother of coal. Obsolete syn. motherham.
AGI
b. Coal material having the appearance and structure of charcoal. It is
friable, sooty, generally high in ash content, and consists mainly of
fusite. AGI
An igniting or explosive device in the form of a cord, consisting of a
flexible fabric tube and a core of low explosive (safety fuse) or high
explosive (detonating cord).
An instrument for regulating the time of burning of a fuse by removing a
certain portion of the composition. It has a movable graduated scale that
regulates the depth to which the auger should penetrate.

Extraction of metals by electrolytic decomposition of their fused salts;
extraction of metals from electrolytically decomposable compounds
dissolved in substances inert under the conditions of electrolysis.

A detonator which is initiated by a safety fuse; also referred to as an
ordinary blasting cap. Atlas
A terminal connection, with a fuse, used on portable electrical mining
machinery.

either the point of fusion or coalescence. Henderson
A specially designed holder with enclosed fuse for connecting a conductor
of a portable cable to the trolley system or other circuit supplying
electric power to equipment in mines.
An instrument for cutting time fuses to length. Standard, 2
That part of an electric detonator consisting of twin metal conductors,
bridged by fine resistance wire, and surrounded by a bead of igniting
compound that burns when the firing current is passed through the bridge
wire. BS, 12
Pyrotechnic devices such as a hot-wire fuse lighter or igniter cords for
the rapid and certain lighting of safety fuse. See:tchesa stick
A friction lock by which a miner may fire the free end of a blasting fuse
by a lanyard. Standard, 2
A temperature scale based on the fusibility of a standard group of
minerals. Used prior to the development of modern furnaces.
