Abstract:
Trepca mine in Stantrg (Kosovo) is a lead, zinc and silver mine.This mine is using fly-ash as a back-fill material since 2010. This material is transported by special trucks from the lignite-fired power stations in central part of Kosova � Obiliq. As the discharged fly ash is a serious environmental problem, it was very important to use this material for back fill in the underground mines, although the considerable amount of ash is available to the cement producers in the region. Using fly ash in the underground mines as a hydraulic filling is very important to increase the safety of mining facilities and setting conditions for the working efficiency of the mining method. Although prior to the use of fly ash in the mines, there were a series of laboratory examinations and reviews on the physical model, after a certain period of time we face with the problem of the layer in the tubes for the vertical transport of the fly-ash. This layer becomes so thick that the tubes have been blocked and it was necessary to replace them. Replacing the tubes was an additional problem, both for the production and for the maintenance. In this paper is presented practical solution how to avoid creation of the layer in the tubes for the vertical transportation of fly-ash in the underground lead and zinc mines in Kosovo.
