Rock Cutting for Deep Sea Mining: an Extension into Poromechanics

Helmons, R. L. J. / Miedema, S. A.

In deep sea mining, the cutting of rock occurs under very high hydrostatic pressures, up to hundreds of bars. Existing cutting models are not capable of describing these hyperbaric effects. In order to develop an improved cutting model, the effects of these high pressures, both in the pores and on top of the rock need to be incorporated in the rock cutting model. Due to need to compute both the behavior of the rock and the pore fluid, a new numerical approach, based on the combination of the Discrete Element Method and the Smoothed Particle Hydrodynamics, is presented. Eventually, this will lead to an improvement of the numerical modeling of fluid-saturated rock mechanics.
