Gassner, FW & Wrench, BP 2010, 'Lined storage facilities for mine waste – considerations and benefits', in R Jewell & AB Fourie (eds), Proceedings of the First International Seminar on the Reduction of Risk in the Management of Tailings and Mine Waste
, Australian Centre for Geomechanics, Perth, pp. 275-281.
The paper presents key design and operational considerations related to the intended performance of a
facility. The paper provides a guide on what lining system concepts result in large, medium or small
environmental benefits. The various components of a lining system and the associated design considerations
and performance in a mining environment are described, both for base lining and capping systems for
tailings and waste rock facilities.
The lining systems discussed include subgrade, single, composite and double lining system, as well as the
drainage system and protection system over the top of the liner. The paper also considers the issue of
durability of various liner materials in mine waste applications.
