Item type:Article, Access status: Open Access , Koncepcja przestrzennego odwzorowania kosztów zwałowania na zwałowisku zewnętrznym(Wydawnictwa AGH, 2010) Kasztelewicz, Zbigniew; Zajączkowski, MaciejOpencast exploitation of mineral deposits requires removing the overburden lying over them and dumping it outside the pit. Most often the overburden is located at the external dumps in immediate proximity from the opening cut. Biggest objects of this kind are created during the building of opencast lignite mines. Large depth on which the deposits are located results in a creation of an external dump with a capacity ranging from a few to few hundred million $m^{3}$. Costs associated with dumping are relevant element of making the deposit accessible. The article presents a concept of spatial model of costs of dumping at the external dump. A hypothetical model of the external dump and terrain's topography on which the dump is located was created. The costs were projected with the use of the dump's block model.
