CASTRO, ALVARO; PINZON, HERNÁN; VARGAS, WILLIAM  and  PINZON, ANDRES. DESIGN PROCESS OF A MINING WASTE BACKFILL. Dyna rev.fac.nac.minas [online]. 2006, vol.73, n.149, pp.53-67. ISSN 0012-7353.

This paper presents the design process and stability assessment of a waste backfill in a limestone quarry method. The study shows the geotechnical and mining features of waste and underground materials affected by backfill. The mainly waste materials are: clay, gravel, and blocks of claystone, sandstone and limestone, all to be disposed by a layered embankment. The constructive method is selected and the stability analysis of deposit and soil foundation was made by equilibrium method without considering deformations.

Keywords : Mine waste backfill; Surface mining; Slope stability; Factor of safety.
