Abstract:Aiming at the difficult problem of key techniques for large-scale location prediction about deep concealed ore bodies of mine, the quantitative methods for determination the effective level of different techniques and methods and the three-dimensional location quantitative prediction technique of deep concealed ore bodies were studied. A series of new technique fruits were introduced, including “Meta-analysis comparison method”, “Effectivity evaluation method”, “Three-dimensional morphological analysis of geological body”, “Simulation of ore-controlling geological factors”, “Three-dimensional quantitative analysis and extraction of ore-forming information” and “Geological three-dimensional visual modeling”. Meanwhile, the application examples of “effectiveness quantitative comparison of the several geophysical methods” in Tongshan Mine and “three-dimensional visual quantitative location prediction of deep concealed ore bodies” in Fenghuangshan Mine were also introduced.
Key words: large-scale location prediction; effectiveness of detection method; Meta analysis; three-dimensional geological modeling; deep concealed ore body
