The aims of EMS are to deal with and solve Estonian mining problems, distribute mining information, organize seminars and conferences. EMS supports students in their studies and encourages students understanding of the industry and commitment to the industry. EMS is representative organization to Government on behalf of the mining industry. EMS student members are important and active part of the organization.

Post-stripping processes and the landscape of mined areas in Estonian oil shale open casts

: The minerals of Estonia are excavated in the amount of 10.5 million m3 per year. yearly 7.4 million m3 of oil shale is mined, and half of this is mined in the open cast mines. The total surface mining amount in Estonia is 6.7 million m3 per year, and 54 % of it stands for oil shale mining. From this data a general rule follows: 1/3 of the volume of mined minerals comes from oil shale underground mining, 1/3 from oil shale surface mining, and 1/3 from surface mining of other minerals.
Mining areas could be divided into five reclamation categories. First - mud excavation area - where mining takes place under water, is no subject for reclamation. Second - clay mining pits - are reclaimed to water storages, ponds or landfills. Third - sand and gravel quarries - are graded or formed as ponds. Fourth - limestone and dolostone quarries - form relatively deep ponds or are filled with waste. Among small-scale mining their reclamation is the most problematical one. Fifth - oil shale, phosphate rock and peat mining areas - are large due to thin horizontal bedding and require special reclamation.
