Numerical simulation of mineral dissolution-precipitation-transportation in a fracture network of rock-mass

In combination with kinetic models of mineral dissolution-precipitation,numerical simulation of calcite dissolution-precipitation and solute transport in an investigative zone is accomplished in this paper in order to study the variation law of mineral dissolution-precipitation and the effect of solute transport.The main conclusions are drawn as follows:(1) Distribution of solute transport is discontinuous because of the effect of fracture network distribution and the solute transportation is ma...
