Effective Use of Geological and Geomechanical Information

"INTRODUCTION The Congress theme ""Improvement of Mine Productivity and Overall Economics by Modern Technology"" is probably beat: addressed by the subtheme allocated to this Plenary Session. It is appropriate that .Theme 1 emphasizes the simple point that effective use of geotechnical information is the key to improving mine productivity. In essence, this means that: (1) geological and geomechanics, (rock mechanics) data must be collected in sufficient quantity and of high quality; (ii) data interpretation must be performed specifically for purposes of engineering design; (iii) innovative design approaches should be used to bring about Improvements in productivity and safety.While, each of these three aspects .may: seem obvious to any mining engineer it is a fact that the above sequence is seldom followed and as a result, mining engineering not infrequently lags, behind other branches of engineering when it comes to design creativity, efficiency and safety.. . After all, mining is still-one of the most hazardous occupations and we are gathered here to discuss, at the highest world professional forum, how to use more effectively the modern technology. This however, does not mean that mining engineers are less capable than other engineers or that their achievements are any lesser; far from it! Mining engineers are the cream of the engineering society on whose efforts depends the welfare of mankind. Moreover, they have produced minerals and coal evergrowing quantities against evergrowing difficulties. Yet, we must and can become even better because we are not making full use of the modern technology and rock mechanics knowledge already at our disposal, and. we are not being innovative enough to the full extent of .our capabilities."
