Geomechanical mapping can help with mine planning.
Geomechanical Mapping – In underground mines, surface mines, and other large excavations, it is vitally important to be able to predict, as accurately as possible, the behaviour of rock, soil and other natural materials and features found in and around a planned excavation.
Knowing how rock and soil will behave in specific circumstances, especially when they are placed under load, is key to being able to safely drill, dig, or blast through these geomechanical conditions during construction. This knowledge is also valuable when it comes to the ongoing management and operation of mines and other excavations, as it will assist with planning, and risk identification and its mitigation.
In order to assess and monitor the status and behaviour of the rock, soil, and other natural materials that occur within the mine, engineers and technical personnel make use of various techniques and methodologies – notably geomechanics.
Geomechanics is the study of geological material and features and consists of several disciplines, the most important being soil mechanics and rock mechanics. Allied to these practices is geomechanical mapping, the collection of high-quality, accurate geomechanical data, which is then analyzed and used to monitor and predict the behaviour of rock and soil within a mine or other excavation.
Geomechanical mapping is used extensively during initial rock engineering design and on an ongoing basis for management and control during the life cycle of a mine or construction operation.
