Industrial waste as an effective material for dam construction

Abstract

The paper presents the issue of tailing supply utilization in dam construction, covers general overview of these wastes produced in Ostrava - Silesian Region as well as experimental results and practical experience with the realization of dam construction in the undermined areas. In Ostrava - Silesian Region mining waste mainly contain the anthracite mining wastes, i.e. tailings - produced in a quantity of cca 9.8 million tons per year. Besides, considerable amount of other industrial wastes (slag, loose ashes, scoria) is produced there as well. These wastes are concentrated in a relatively small area of the region. From the facts listed above we can deduce that the present state of ecology is abject there. Provided that the major part of these wastes would be put back into the mined-out areas or utilized as building material, there is a certain possibility to protect the environment. Utilization of formerly mentioned wastes (slag, loose ashes, scoria) in road engineering is described in the references.

Opracowanie przedstawia zagadnienie wykorzystania odpadów poflotacyjnych do konstrukcji stawów osadowych, zawiera ogólny przegląd tego rodzaju odpadów produkowanych w rejonie Ostrawy oraz prezentuje wyniki i doświadczenia praktyczne zdobyte podczas eksperymentalnej konstrukcji stawu osadowego zlokalizowanego na obszarze poeksploatacyjnym.
