Abstract
The evolution of the Lornex tailings disposal facility, in particular the Lower L-L Dam, throughout the design and construction phases is presented with the emphasis on how economic considerations have dictated this process. Major episodes described here include: the early conversion to an energy efficient t wo-dam storage scheme, the reduction of the size of the L-L Starter Dam, the buttressing of the Starter Dam in an area involving soft foundations, and the development of hydraulic means to use cycloned tailings sand for annual raising of the L-L Dam. Extensive instrumentation was installed to monitor the performance of the L-L dam in critical construction periods. This helped the designers to adapt the design of the dam to its actual performance in order to ensure its safety.

Evolution of Design and Construction of Lornex L-L Tailings Dam
The evolution of the Lornex tailings disposal facility, in particular the Lower L-L Dam, throughout the design and construction phases is presented with the emphasis on how economic considerations have dictated this process. Major episodes described here include: the early conversion to an energy efficient t wo-dam storage scheme, the reduction of the size of the L-L Starter Dam, the buttressing of the Starter Dam in an area involving soft foundations, and the development of hydraulic means to use cycloned tailings sand for annual raising of the L-L Dam. Extensive instrumentation was installed to monitor the performance of the L-L dam in critical construction periods.
