GMB - Geomechanics and Mining

Play it safe.

This expression might be used on any occasion in every day life but it has a special meaning in mining. The surrounding rock does not only prove to be a big and unpredictable threat to the miners but also to investments of the mining infrastructure and equipment. The department for geomechanics establishes the background for the assessment of the geomechanical condition of a mine layout. On the basis of gained data from instrumental measurements (e.g. stresses in the rock mass, transverse strain in pillars, seismic monitoring, tests on the quality of the back fill, etc.) and in addition to the data provided by the customer (e.g. ground subsidence, geological fractures, etc.) a complex analysis of the condition that the rock mass is in is carried out continuously and then continued by a constant feed of new data. Of course any particular question concerning the special subject rock mechanics in saliniferous formations can be answered.

Like a Swiss army knife.

The department for mining can be used in a similar multifunctional way: many different tasks and projects exist, all around the globe: deposit modelling, mining layout plans for underground excavation companies or for solution mining, securing of abandoned mines including shaft seals, technical feasibility studies with different degrees of detail, cost estimation using CAPEX/OPEX, construction of optimised instrumented measurements for  solution mining, geological mapping and so forth.
