These are written records (files, books, company brochures etc.), which are found in practically all the recorded collections and museums, alongside the objects kept there.

Miner’s lamps, a collective term used in mining for all lighting equipment used underground. (following: Das kleine Bergbaulexikon, [The small mining glossary], 1998)

This object group encompasses mining-related map materials, including maps showing colliery sites or graphical representations based on surveys performed above and below ground, known as Grubenrisse [mine layouts].

Image, film and audio material particularly containing historical images of collieries and audio-visual documentation of underground mining work.

Tools used in mining work. In German-speaking countries, the miner's toolset is known as a "Gezähe". (following: Das kleine Bergbaulexikon [The small mining glossary], 1998)

Uniforms worn by mining officials and miners on festive and formal occasions.

This is protective clothing designed to withstand the tough working conditions underground.

Objects with a close connection to mining customs, miners’ associations as well as personal mementos

Objects in the areas of geology, mineralogy and palaeontology, frequently used to document the structure of various deposits

Compressed air and electricity are practically the only sources of energy suitable in underground mining. Compressed air is suitable for powering all machinery, while electricity is primarily used for rotationally powered machines. (following: Grothe, Lexikon des Bergbaues, [Mining Lexicon] 1962)

Facilities enabling communications to be relayed from aboveground to underground, and enabling people underground to communicate with one another

Manriding, movement of people on foot while underground, using passenger trains, overhead monorails, floor conveyors, band conveyors or chairlifts. (following: Das kleine Bergbaulexikon [The small mining glossary], 1998)

Transportation encompasses all installations, systems and measures employed in the movement of mineral raw materials, the worthless debris, materials and individuals, and in powering such facilities. (following: Das kleine Bergbaulexikon [The small mining glossary], 1998)

Equipment for accidents and incidents, particularly firefighting appliances and mine rescue equipment.

Blasting work, all the activities, with the exception of making blasting boreholes, that are necessary for blasting, meaning the forceful rupture and fragmentation of target objects through the application of explosives. (following: Das kleine Bergbaulexikon [The small mining glossary], 1998)

Extraction, loosening of coal and other deposit content from the hard rock with the aid of the extraction procedure. (following: Das kleine Bergbaulexikon [The small mining glossary], 1998)

Objects, systems and support elements for keeping mining cavities open, also for face supports incl. walking props and for removing the lining.

As lifelike, scaled-down replicas, models are used to explain the functional methods of technical plant and machinery.

Diorama, a plastic, painted rendering usually assembled within a display case and used as a teaching aid. (following: dtv-Brockhaus-Lexikon, 1986)

The term for the geodetic survey of the mining claim performed by mining surveyors

Markscheide is the word for the lateral boundary line of a mining claim, and which is determined by a line to the earth’s surface, and which continues as an imaginary plane to the centre-point of the earth. (following: Das kleine Bergbaulexikon [The small mining glossary], 1998)

Machines and accessories for making cylindrical cavities in the rock, for prospecting, extraction, alignment or lining work, or for preparing blasting work.

Meaning a miner's personal effects for use underground, and which do not directly serve as work tools. These might be the miner's lunch box or snuff pouch.

Constructing a horizontal or inclined tunnel

The purpose of mine ventilation is to allow people and animals in the mine to breathe, and to supply the air needed to fuel the miner's lamp, and to thin and dissipate the stale or toxic air and firedamp that accumulates in the mine, until it has been rendered harmless. (following: Grothe, Lexikon des Bergbaues, [Mining Lexicon] 1962)

Mechanical installations and accessories (such as pipelines), which served to keep the mine dry, to collect water ingressing into the mine, and, if required to purify it and pump it away.

Sinking, constructing a mine opening such as a shaft, blind shaft, borehole or bunker using various techniques such as blasting or drilling large boreholes. (following: Das kleine Bergbaulexikon [The small mining glossary], 1998)
