Abstract
Having abandoned mine workings, the closure strategy of mine working openings is important in terms of maintaining long-term stability. The paper describes the process of closing the mine workings in the uranium deposit Rožná using unconsolidated backfill. Before backfilling, it is vital to carry out preparatory work underground for ecological, technological or economic reasons. The mine workings backfilling using unconsolidated backfill is preceded by calculations to determine the quantity of the backfill. The stability of the mine workings opening is achieved using a closing sinking platform made of reinforced concrete. The abandonment procedure is framed within the legislation of the Czech Republic, grounded in the handbook by the National Coal Board of Great Britain (NCB, 1982), and has been gradually amended according to the experience with disused mine workings. The Czech legislation dealing with mine abandonment is very advanced and may be applied to modify foreign legislation. The abandonment procedure based on Decree 52 (1997) proposed in this paper is complemented by safety features such as micropilots in the sinking platform or shaft lining check-up before the backfill. The proposed method is applicable in mines with analogous specific conditions, such as mines free of gas hazards and coal dust. The paper concludes with an analysis of risks likely to occur due to incorrect mine closures.
期刊介绍：
Acta Montanistica Slovaca publishes high quality articles on basic and applied research in the following fields:
geology and geological survey;
mining;
Earth resources;
underground engineering and geotechnics;
mining mechanization, mining transport, deep hole drilling;
ecotechnology and mineralurgy;
process control, automation and applied informatics in raw materials extraction, utilization and processing;
other similar fields.
Acta Montanistica Slovaca is the only scientific journal of this kind in Central, Eastern and South Eastern Europe.
The submitted manuscripts should contribute significantly to the international literature, even if the focus can be regional. Manuscripts should cite the extant and relevant international literature, should clearly state what the wider contribution is (e.g. a novel discovery, application of a new technique or methodology, application of an existing methodology to a new problem), and should discuss the importance of the work in the international context.
