Abstract:-Oil shale mining is a crucially important industry for the Estonian economy. More than 85 percent of electricity in Estonia is produced from oil shale. The oil shale deposit is located in North-East Estonia. The oil shale bed descends three meters per kilometer to the south. The oil shale seam contains interlayered limestone. Some of it is used as low class aggregate rock and the rest is waste rock which is stored in waste rock heaps. Crushing, separating and sampling tests of the waste material are currently… Show more
