Record 1 2016-02-26

English

Subject field(s)
  • Mining Dangers and Mine Safety
  • Underground Mining
DEF

The sudden failure of walls or pillars in a mine caused by the weight or pressure of the surrounding rocks, and accompanied by a violent release of energy.

CONT

Rock bursts. In areas of very deep mining, as additional weight is supported by the pillars on the coal face, stresses may so build up that the yield point is reached. If the coal pillars, the roof, or the floor are able to yield gradually, the effects of the stresses are relieved by floor heaving, or by pillar or roof failure. Where the coal or the associated rocks are particularly strong and depths are much above average, these stresses may be relieved by rock bursts, which are relatively violent outbursts of the coal into the rooms and entries. Frequently, a large volume of gas(usually methane) is suddenly released during a rock burst in a coal mine.

OBS

for "coal burst" : Rock bursts and "coal bursts" in coal mines are generally designated by the term "bumps" or "bounces". A large proportion of these "bumps" or "bounces" are actually "coal bursts" due to fracturing of pillars and remnants and need not involve any fracturing of roof or floor rock.

OBS

for "air blast" : In former years rock bursts were sometimes referred to as "air blasts". This name originated from the fact that large quantities of rock loosened by some of the larger rock bursts displaced quantities of air, with the result that a blast of air passed through the mine workings.

DEF

A timber frame to support the roof, sides, and sometimes the floor of mine roadways, or shafts.

Subject field(s)
  • Blasting Work (Mining)
DEF

A term applied to the method of blasting in which large charges are fired in small adits or tunnels driven, at the level of the floor, in the face of a quarry or slope of an open-pit mine.

OBS

Coyote blasting is best adapted to faces from 80 to 175 ft. high, where the surface is irregular and where a large tonnage of rock is to be broken at one blast. In high banks, the use of supplementary churn drill holes, about one-third the depth of the face, gives a more regular line of break.

Subject field(s)
  • Ovens, Furnaces and Boilers (Heating)
  • Steam-Powered Machines and Condensers
CONT

Next form of haulage at Cwmdu Colliery was the installation of a small winch in October 1934. The steam to drive this winch was provided by a vertical boiler, 8 feet high and 5 feet in diameter. A small engine house had been constructed from round bush poles, roofed with galvanised corrugated iron, and it had a concrete floor... The Cwmdu Colliery syndicate had planned to replace its early vertical boiler with the horizontal boiler to give the mine an increased flow of steam power.

Domaine(s)
  • Fours et chaudières (Chauffage)
  • Machines à vapeur et condenseurs
CONT

Les chaudières verticales à foyer intérieur, ont été imaginées pour gagner de la place en développant en hauteur la surface de chauffe. En général, ces chaudières s'emploient quand l'emplacement est restreint et quand il s'agit de faible puissance. Si perfectionnées qu'elles soient, elles utilisent toujours moins bien la chaleur qu'une chaudière horizontale de valeur égale, en vertu de leur forme même.
