Abstract
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
Highlights
Lignite was mined in the region of Ośno Lubuskie in the years 1850-1962
The deposits were mined using the retreat mining method, the workings were not filled, only the shafts were filled, which resulted in different kinds of sinkholes on the ground surface
The history of mining near Ośno Lubuskie can be traced back on the basis of rather rudimentary archive materials, geological documents and mining maps, which are dispersed over different archives
Summary
Lignite was mined in the region of Ośno Lubuskie in the years 1850-1962. There were several dozen mines, most of them operated for a short time and on a small area. Data obtained by airborne scanning can be used Data obtained in this way enable building high resolution models as well as separating from the cloud of points the information that refers to the terrain cover e.g. buildings and foliage, which makes it possible to build a real terrain model. This is useful for recognizing underground post-lignite mining areas, which at present are located in forest areas [1]
