Economic parameters of drilling and blasting overburden on the pit mines black coal mine 'Banovići'

In this paper are analyzed economic parameters of drilling and blasting overburden on pit mines RMU Banovici. On the pit mines "Cubric" and "Grivice" was done blasting with new types explosion materials. Blasting is performed with emulsion explosives "Handibulk" produced by ICI Explozives England. For used explosives defined optimal parameters of drilling and blasting for rock mass on overburden. Costs of production process drilling and blasting estimated 0,321 (€/m3cm), and single part of all processes are getting with graph.
