DEVELOPMENT AND APPLICATION OF COMPUTER MODELS TO ANALYZE, EVALUATE AND COMPARE DIFFERENT OPTIONS OF NEW MINING TECHNIQUES USING COMENTED BACK-FILL IN BASE-METAL-MINING.

THE COMPUTERIZED MODELS TO BE DEVELOPED SHALL BE CAPABLE TO ANALYZE, EVALUATE AND COMPARE DIFFERENT OPTIONS FOR THE METHOD AS A WHOLE AS WELL AS FOR PARTS OF IT, THUS ENABLING THE PLANNING ENGINEERS TO QUANTITATIVELY DETERMINE THE SOLUTION(S), WHICH IS(ARE) OPTIMAL IN TERMS OF TECHNOLOGY AND/OR ECONOMY. THE RESEARCH SHALL BE CARRIED OUT IN CLOSE COLLABORATION WITH SACHTLEBEN BERGBAU GMBH AND ITS MINE MEGGEN, WHERE TECHNOLOGICAL INVESTIGATIONS AND RESEARCHES INTO THIS MINING METHOD ARE BEING CARRIED OUT.

THE RESEARCH COMPRISES 6 TEPS :

1. MODELLING THE DEPOSIT USING GEOSTATISTIC TECHNIQUES

2. ANALYZING AND FUNCTIONAL FORMULATION OF THE TECHNICAL INTERDEPENDENCIES OF THE SYSTEMS COMPONENTS AND THE SYSTEM AS A WHOLE,

3. ANALYZING AND EVALUATING (AND FUCTIONAL FORMULATION) OF THE ECONOMIC FACTORS OF INFLUENCE (COST, PROCEEDS, DILUTION-AND EXTRACTION RATIO),

4. ANALYZING AND FORMULATING THE EXTERNAL ECONOMIC INFLUENCES (MARKET TRENDS, PRICE FLUCTUATIONS ETC.)

5. DEVELOPMENT OF A SIMULATION MODEL TO EVALUATE DIFFERENT METHODS AND OPTIONS OF THE MINING PROCESS, WHICH MODEL WILL BE BASED ON STEPS 1-4,

TESTING AND VERIFICATION OF THE MODEL BY APPLYING TO SOME PRACTICAL CASES.

THE RESEARCH AND THE FINAL MODELS FOR MEGGEN WILL BE ALSO USEFULL FOR SIMILAR DEPOSITS OR MINES WITH ONLY LITTLE ADAPTION.
