6 Potential Environmental Effects Of Uranium Mining

A uranium minemill complex in the united states occurred near church rock, new mexico, in june 1979. a breach of an earthen dam containing solid and liquid tailings caused the release of 1,100 tons of radioactive mill waste and 95 million gallons of mine effluents.

Abutment in coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Radioactive Waste From Uranium Mining And Milling

Radiation facts. regardless of how uranium is removed from rock, the extraction process creates radioactive wastes. if not managed properly, mining waste and mill tailings can contaminate the environment. uranium is a naturallyoccurring radioactive element that has been mined and used for its chemical properties for more than a thousand years.
