east of the present inn building the mining and history society of the mining town of lautenthal bergwerks- und geschichtsverein bergstadt lautenthal von 1976 e.v. built a working model of mining equipment between 1992 and 1998 in order to show the original function of the area. the water wheel at a scale of 1:2 with a six-metre diameter is .
small groups of part-time miners used shovels and primitive equipment. scottish miners had been bonded to their 'maisters' by a 1606 act 'anent coalyers and salters'. a colliers and salters scotland act 1775 , recognised this to be 'a state of slavery and bondage' and formally abolished it; this was made effective by a further law in 1799.
mining can be conducted on more than one bench at a time, and access to different benches is done with a system of ramps. the width of each bench is determined by the size of the equipment being used, generally 20–40 metres wide. downward ramps are created to allow mining on a new level to begin.
mining was under the control of the state but the mines may have been leased to civilian contractors some time later. the gold served as the primary medium of exchange within the empire, and was an important motive in the roman invasion of britain by claudius in the first century ad, although there is only one known roman gold mine at dolaucothi in west wales.

due to the distance from earth to an asteroid selected for mining, the round-trip time for communications will be several minutes or more, except during occasional close approaches to earth by near-earth asteroids. thus any mining equipment will either need to be highly automated, or a human presence will be needed nearby.

throughout the medieval period these technical innovations, and the traditional techniques, coexisted. their application depended on the time period, and geographical region. water power in medieval mining and metallurgy was introduced well before the 11th century, but it was only in the 11th century that it was widely applied.
pre 1900. although some deep mining took place as early as the late tudor period in the north east, and roughly the same time in the stuart period along the firth of forth coast, deep shaft mining in britain began to develop extensively in the late 18th century, with rapid expansion throughout the 19th century and early 20th century when the industry peaked.
