Opinion on a Reliable Rock Engineering Tool-Box for Mining Industry by Eivind Grøv* in Aspects in Mining & Mineral Science_ Aspects in Mining & Mineral Science
Abstract
Along
the development of human being, there are several important inventions that
completely change the way we live. Such inventions may be “fire”, “electricity”, and now
“Information Technology - IT”. It is difficult to imagine our life now without
IT, and it is the same situation in mining industry. It is quite common today
that rock engineering projects in general, and particularly mining projects are
planned and developed with help of computer added tool-numerical model. The
model can be performed in 2D or 3D in order to provide engineering parameters
for decision making. The engineering parameters can be development and
distribution of stress, strain, and displacement for stability analyses. It can
also be vibration and seismicity related to mining process, and so on…. Information
provided from numerical models is always an important source of information
making decision. However, decision makers are always “stuck” with a question
that “How can I trust the information from numerical model?” In our opinion, it
is a long process with a more complete toolbox rather than only numerical model
alone for appropriately to answer to that question. With over 50 years of
research and development, SINTEF has developed a reliable rock engineering tool
to deal with the challenges. The tool is a combination of three components
“investigation tools”, “numerical modelling”, and “site monitoring”. We use the
term “TRIPOD” for the methodology
