KONTROLA FRAGMENTACIJE MINIRANJEM
Description (Dublin Core)

The degree of fragmentation influences the economy of the excavation operations. Characteristics of blasted rock such as fragment size, volume and mass are fundamental variables effecting the economics of a mining operation and are in effect the basis for evaluating the quality of a blast.
The properties of fragmentation, such as size and shape, are very important information for the optimization of production. Three factors control the fragment size distribution: the rock structure, the quantity of explosive and its distribution within the rock mass.
Over the last decade there have been considerable advances in our ability to measure and analyze blasting performance. These can now be combined with the continuing growth in computing power to develop a more effective description of rock fragmentation for use by future blasting practitioners.
The paper describes a view of the fragmentation problem by blasting and the need for a new generation of engineering tools to guide the design and implementation of blasting operations.

Stupanj fragmentacije odminirane mase ima utjecaj na ekonomsko poslovanje eksploatacije. Značajke odminirane mase kao veličina komada stijene, volumen i količina su osnovni čimbenici ekonomskih efekata rudarskih radova i osnova su razvoja kvalitete minerskih radova.
Svojstva odminirane stijenske mase kao oblik i veličina važni su elementi za postizanje optimalne proizvodnje. Tri su osnovna čimbenika koji direktno utječu na fragmentaciju odminirane mase: struktura stijenske mase, količina eksploziva i način aktiviranja minskih bušotina, odnosno rasprostiranje energije eksploziva u stijenskoj masi.
Koncem zadnjeg desetljeća zbio se znatan napredak u mjerenju i analizi minerskih značajki. U kombinaciji s razvojem i snagom računala omogućen je značajan razvoj opisa fragmentacije za buduće minerske radove.
U radu se opisuje i daje pregled problematike fragmentacije kod miniranja i primjene nove generacije inženjerskih pomagala za projektiranje minerskih operacija.
