Přepočet zásob a návrh na dotěžení ložiska v kamenolomu Kožlí u Čížové - studie

Abstract

Mining and crushed aggregate production in the “Kožlí u Čížové” quarry have a longtime tradition. With an annual aggregate output up to 100 000 t the quarry is ranked among the smaller Czech quarries. An aim of the thesis is own alternative recalculation of reserves using a horizontal line method in a allotment according to program of an early development, a routing and a mining. The recalculation result is compared with a calculation using spatial simulation of deposit method. In the thesis a study of an outline of mining plan in the part of the allotment which has not yet been explored followed by the mining plan in the whole quarry up to the level of final recess is elaborated. Results of an alternative recalculation of reserves and an estimate of future quarry lifetime period regarding planned mining progress are summarized in conclusion.
