UTILIZATION OF WASTE ROCK FROM OIL SHALE MINING

The paper deals with utilization of oil shale mining waste rock in Estonia. Crushed waste rock is utilized as an aggregate in civil engineering in frost-free environmental conditions and in road building in unbound mixtures where required resistance to fragmentation LA ≤ 35%. This study determines areas of utilization of waste rock and shows that waste rock aggregate

Reduction of Oil Shale Losses - CORE

Oil shale utilisation losses reach 70% in some cases. These are closely related to legislation, backfilling and waste rock usage. Much smaller sections include production of oil, electricity and chemicals in which most of the research and development is performed today.

In several cases selectivity is the key solution for extraction, separation or processing. Fine separations has not shown good results for oil shale, but limestone fine separation, granulating or jigging should still be analysed with more options. In addition dry separation with sizers, drum crushers and roll-crusher sieves should be considered.

oil shale National Geographic Society

Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar hydrocarbons. The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas.

Porosity and Bulk Density of Sedimentary Rocks

Average values for the porosity of sedimentary rocks have been given by Barrell (1914) as: shale, 8.2 percent; sandstone, 14.8 per­ cent; limestone, 5.3 percent; and all sedimentary rocks, 8.5 percent. Additional data since the publication of Barrell's summary indicate that the average value of 8.2 percent for the porosity of shale may be low.
