An Arches is a

the wall or rock on the upper side of steeply inclined deposits.

The wall at the edge of a pit. They are generally very tall and very steep

A safety barrier constructed from material on theside of a ramp opening to prevent vehicles from entering over it

angle of inclination of the vein from the horizontal plane

A platform attached to a winding rope used for transporting personnel, supplies and equipment in a mine shaft.

Refers to the slope of a wall.

A natural opening mode factures in coal beds.

an ore deposit of tabular form that lies horizontally or slightly inclined

An excavation made at the bottom of a shaft to collect water.

Ground steepness. Levels, GPS can be used with pegs to setout cut/fill values formachines to follow to achieve correct _

A vertical wall of a drive in the direction which the mine is heading.

A platform attached to a winding rope used for transporting personnel, supplies and equipment in a mine shaft

The expansion of shot ground after a blast

the term applied to the timbering or concrete around the mouth or top of a shaft

An underground drive that runs across a coal seam.

- vertical or diagonal opening between levels to permit movement of ore by gravity

The slope of drives, cross-cuts, inclines, and declines.

A roadway or ventilation passage that interconnections main workings.

The outer edge of a hole.

mined rocks that do not contain minerals

Roof of an underground area

thin deposit of minerals between definite boundaries.

A tunnel driven at right angles to the main headings

A steel structure built around a mine shaft for supporting winding systems, cages and skips.

Horizontal opening in or near a mineral deposit and parallel to the course of the vein or long dimension of the deposit

a vertical excavation in a mine extending downward from the surface or from some interior point as a principal opening.

An entrance to an underground mine

A block of coal or rock that hasn't been mined.

An open space left in an underground mine as a result of using the stoping method to remove wanted ore.

a vertical or inclined opening driven downwards from a point insidethe mine for connecting with a lower level

underground “room” or working area from which ore is removed.

The initial cut in the ground when excavations are to commence in a new area.

A wall or structure used for blocking off an underground opening.

Waste material (rock) used to fill excavated holes/areas.

- a horizontal opening driven from the shaft to avein across the course of avein in order to reach the ore zone.

A roadway or cross-cut in an underground operation

Loose material pushed to anedge, generallyused toprevent vehicles from driving off highwalls or outside designatedroad

The bottom edge of a high wall, rill or digface.

a horizontal or nearly horizontal passage driven from the surface for working or dewatering a mine

Horizontal underground workings that are not connected to the main shaft.

the line of intersection between vein and the horizontal plane

What is a Fill?

Outcrop

Refers to a level once its has been reduced to a datum

A wall of separation (usually temporary) to barricade designed to direct air flow (or restrict it).

–horizontal passage or drift which starts from shafts and are commonly spaced at regular intervals in depth

the wall or rock under a vein or other steeply inclined mineral formation.

An explosive/blasting material used for loading a blast hole

A main underground passage or roadway system

a mineral deposit that can be worked at a profit under existing economic conditions.

A Backfill is

Refers to a dig face that has been excavated slightly further from belowthe crest of the face.

Boreholes are

a vertical or inclined opening driven upwards in ore from a level.

Horizontal pillars that run accross a coal seam.
