In Poland, apart from opencast mining, brown coal (lignite) was also mined by underground methods. This is related to glaciotectonic disturbances leading to deposition of Miocene coal in the form of folds (synclines and anticlines). The highest number of underground brown coal mines in the 19th century was recorded in western Poland. In …
