Analiza zdrobljenosti kamnine z obdelavo digitalnih slik miniranega kupa

Pelicon, Jure (author), Kortnik, Jože (mentor)

Pravilna ocena in analiza granulacije mineralne surovine po miniranju je ključnega pomena za učinkovito bogatenje agregata v primarni fazi drobljenja. Podcenjevanje problematike mletja po miniranju lahko privede do prekomerne obrabe drobilca, kar doprinese k višjim proizvodnim stroškom. Za reševanje problematike pridobivanja ustrezne granulacije so danes na voljo računalniške programske rešitve, s katerimi lahko enostavno in hitro pridobimo podatke o granulaciji takoj po miniranju. V diplomskem delu sem za analizo granulacije uporabil programsko opremo WipFrag, s katero sem analiziral granulacije petih miniranj v dveh kamnolomih podjetja Salonit Anhovo. Cilj diplomskega dela je bila primerjava granulacijske sestave miniranj s prodajno granulacijo podjetja Salonit Anhovo ter podajanja rešitev doseganja optimalnega miniranja za namen približevanja prodajni krivulji. Primerjava analiz je pokazala, da bi bilo mogoče z ustreznimi rešitvami še izboljšati posamezne faktorje pri miniranju, zaradi katerih bi posledično dosegali boljše drobljenje pri samem miniranju. Rešitve za doseganje ustreznejše granulacije minirane kamnine lahko izvedemo pri miniranju na različne načine, ki jih predstavljam v diplomski nalogi.

Abstract

A proper assessment and analysis of granulation after blasting is crucial for effective enrichment of agglomerate in the primary phase of crushing. Not knowing about problems of non-proper grinding/milling granulation after blasting can lead to excessive crusher wear and consequently to higher production costs. The problems of obtaining good-quality granulation can nowadays be solved with computer software solutions, which can be used simply and quickly in order to get data about granulation immediately after blasting. In my thesis WipFrag software is used for granulation analysis, analysing five blastings in two quarries of Salonit Anhovo. The aim is comparison of granulation composition of blasting with that of sales-intended granulation of Salonit Anhovo as well as delivering solutions for the achievement of optimum blasting with the intention of approching the sales curve. Comparison of analysis has shown that by using suitable solutions it would be possible to improve individual factors in blasting, resulting in better crushing in the blasting process. Solutions for the improvement of granulation of blasted rocks through granulation can be obtained in various ways, all of which are presented in this thesis.
