The surface miner sustainable technology introduction for oil-shale mining in Estonia

摘要: The paper introduces a high-selective oil-shale mining technology and the first results of surface miner Wirtgen 2500SM tests. allows to decrease loses from 10-15% up 5-7%. Mining process has lower disturbing impact, which is topical in open pits quarries especially densely populated areas. low level dust noise emissions also very’ vibration are arguments mine oil shale with instead drilling-blasting operations. risk analysis for testing was elaborated.
