The article discusses the suitability of coal mining waste rock as a backfill material in reinforced earth structures and bridge abutments. Coal mine waste rock has not hitherto been used in reinforced earth structures and it remains to be proven whether its mechanical, physical and chemical characteristics are suited to backfill requirements in such structures. Details are given of the construction of a retaining wall at donisthorpe mine in 1980 to evaluate the long-term properties of minestone as backfill. Measurements of temperature and stress in the structure are examined. An intensive corrosion study is being carried out to assess the effects of burial of element materials to evaluate the corrosiveness of minestone backfills. (TRRL)
