Abstract
In the mines of the Baltic oil shale basin, extensive industrial tests of different variants of the chamber mining system have been carried out for several years. In order to correctly determine the parameters of the system, the behavior of rock pressure was studied at the mine No. 3 of the Slantsy Combine, in particular, the stability of the pillars was investigated. The commercial oil shale bed with a total thickness of 2–3 m is almost horizontal at a depth of 30–100 m under the conditions of the basin and consists of four layers of oil shale and three rock partings. In the roof and floor of the seam, limestones are interbedded with clay and oil shale.
