Introduction to mining history 1830 - 1920 Mining was the key to technical, social and scientific development in many parts of the world. On the other hand, mining was a not harmless and quite sacrificing profession. The mechanization of the mines, the increasing level of knowledge and the change to porphyric, i. e. large-scale deposits, forced the mining industry to adapt its working methods time and again. Here, the period from 1830 to 1920 is to be evaluated more precisely. Between 1830 and 1920, technical progress in
mining was already clearly visible, and mining methods differed
markedly from earlier times. For technical reasons, the metal
concentrations were still remarkably high (silver was from 1% to
3%, copper was initially from 20% to 25% later at 3 to 8%). This
resulted in a rapid deepening of the mines. In some shafts in
the Harz and also in other districts, the miner was able to
reach the mine in a relatively short time with the help of a "Men
Engine". The technical progress made it possible to increase
production while deepening the shafts considerably. In general,
the mining industry was already geared towards mass production
and efficiency during this period. Rich ore bodies were
exploited throughout in vein-shaped (here)
or sedimentary deposits,
(here).
Only the provision of low-cost energy was not guaranteed or very
difficult. Water, steam engine or horsepower were the most
important sources of energy. The time span is generally
known-indicated by:
