Rock mechanics

From Wikipedia, the free encyclopedia

Rock mechanics is the theoretical and applied science of the mechanical behaviour of rock and rock masses; it is that branch of mechanics concerned with the response of rock and rock masses to the force fields of their physical environment. Rock mechanics itself forms part of the broader subject of geomechanics which is concern with the mechanical responses of all geological materials, including soils. Rock mechanics, as applied in mining engineering practice, is concerned with the application of the principles of engineering mechanics to the design of the rock structures generated by mining activity, e.g. tunnels, mining shafts, underground excavations, open pit mines. It also includes the proper design of rock bolting patterns.
