The paper presents available information about history of lignite mining in region of Górzyca (north-west part of Ziemia Lubuska - Western Poland). Lignite mines operated here in years 1850-1938. The paper describes briefly the history of particular mines:„Lord”, „Karl Ferdinand”, „Humboldt” and „Finke”. Also underground mining in complicated geological condition (glaciotectonic deformations) was presented. The paper is based on remained German archival materials and also historical map: geological and topographic.

The process of the construction of engineering structures situated within glacitectonically disturbed areas cause the necessity to link engineering operation with knowledge of geological processes. One of the examples of such a structure was the construction of the west bypass of Zielona Góra. The roadworks were connected with the necessity of deep excavations into glacitectonically disturbed soil structures. This caused intense changes in the soil mass and - as a consequence - loss of slope stability and the construction of landslides. At the construction stage numerous landslides were already active, which additionally increased during intensive road use. In spite of technical stabilization, there was a risk of loss of slope stability, which is a consequence of stresses in soil mass and engineering activity. This article presents the results of the monitoring of the slope stability during intensive road exploitation.

The paper presents the possibilities of using data obtained by airborne laser scanning for identifying areas where lignite used to be mined. The technology of airborne laser scanning presented in the paper as and its results have a vast potential in terms of identifying local terrain deformations. The paper also presents the history of lignite mining in the region of Ośno Lubuskie (the north-west of Ziemia Lubuska - western Poland). It describes underground mining in complicated geological conditions (glaciotectonic deformations). The paper is supplemented with historical maps showing the locations of the mines

The work describes the discovery of lignite deposits by C.A. Pohlez in 1838 near Zielona Góra that initiated extraction of this mineral coal by several mines. Exploitation of lignite in Zielona Góra and its neighbourhood was taking place in the years 1841-1948. The article describes only the fi rst years of mining and creation of the Gewerkschaft "Consolidierte Grünberger Gruben", which embraced almost all mines in the vicinity. Extraction of lignite was conducted in the Wilkanowo and Słone villages near Zielona Góra, and also in the western part of the city. The text describes areas where particular mines belonging to the Gewrkschaft worked and presents well-known locations of the oldest mineshafts. It also presents available historical maps containing data on mining in the area of Zielona Góra and, on the basis of few preserved source materials and the 19th-century geological and mining literature, certain data concerning employment and the amount of extraction. The article introduces us also to the economic situation of the 19th-century Gewerkschaft.
