Abstract

Eksploatacijsko polje „Bukova glava-Vranović“ u vlasništvu je tvornice cementa NEXE d.d., krovne tvrtke NEXE Grupe koja se bavi proizvodnjom građevinskog materijala. Iz eksploatacijskog polja dobiva se sirovina za proizvodnju cementa strojnim iskopom i miniranjem. Eksploatiraju se lapori i vapnenci, te njihove primjese. Kemijski sastav mineralne sirovine za proizvodnju cementa strogo se prati jer je nužan za proizvodnju samog cementa. Miniranju prethode brojne pripremne radnje, kao što su označavanje minskog polja, bušenje i bušotina na minskom polju, te izrada plana miniranja. Opisan je postupak pripreme sirovine za proizvodnju cementa. Izvedeno je pokusno miniranje na četiri minska polja različitog promjera patrone eksploziva. Računalnim softverom WipFrag izrađena je granulometrijska krivulja svakog minskog polja, te su međusobno uspoređene.

Abstract (english)

The exploitation field "Bukova glava-Vranović" is owned by the NEXE d.d. cement factory, the main company of the NEXE Group, which is engaged in the production of construction materials. Raw material for cement production is obtained from the exploitation field by mechanical excavation and blasting. Marls and limestones and their admixtures are exploited from the field. The chemical composition of the mineral raw material for the production of cement is strictly monitored because it is necessary for the production of the cement itself. Blasting is preceded by numerous preparatory works, such as marking the drilling pattern, drilling blast holes, and creating the blasting design. The process of preparing raw materials for cement production is described. Experimental blasting was carried out on four sections with different diameter of the explosive cartridge. The granulometric curve for each blast was created with the computer software WipFrag, and they were compared with each other.
