Rock strength

Knowledge about rock strength is of key importance for taking decisions in developing deposits and reservoirs. Only based on rock strength data quarrying, tunneling and drilling progress can be planned and executed. However, the properties of rocks cannot be predicted from log data alone or based on literature. We consider an experimental determination of the relevant parameters indispensable for this purpose.

We carry out all kinds of deformation tests from simple Brazilian and unconfined compressive tests via triaxial compressive tests to more complicated triaxial extension tests and even purely elastic compressibility tests. By this measure we achieve the most important rock strength parameters: unconfined compressive strength, cohesion, coefficient of (internal) friction, Young’s modulus, Poisson’s ratio, bulk modulus, Biot coefficient and many other important moduli. Since we combine deformation experiments with ultrasonic measurements of P- and S-waves we provide both, static and dynamic moduli.

Moreover, you can expect the successful execution of customised and complex test sequences from us. We develop the concept and methodology for solving your special questions - up to device development for special measurement engineering tasks.
