Abstract
POST-STRIPPING PROCESSES AND THE LANDSCAPE OF MINED AREAS IN ESTONIAN OIL SHALE OPEN CASTS I. VALGMA Tallinn Technical University, Mining Institute 82 Kopli St., Tallinn 10412, Estonia The present study describes creating a digital map of oil shale surface mining technology and evaluating mining influences on the landscape. The data from the digital map of the Sirgala open cast show a constant increase in the overburden thickness. Overburden material thickness influences directly the future landscape but it also sets limits to stripping equipment parameters and productivity. The present open cast landscape was divided into four classes: afforested area, area with poor vegetation, graded area, and spoils. The second purpose of the study is saving information in an easily accessible form for the future. For this purpose geographic information system for mining is used. trilobite@argus.chemnet.ee
