Every year, the number of exploited mine workings necessary to seal mines increases in world. As a result experiments, technologies are developed that allow slurry be pumped fill free rock spaces or liquidate mass discontinuities. The preparation can divided into: subsurface and surface injection. Due pressure forces sealing move, following distinguished: gravity effectiveness work is determine...

Geological isolation of nuclear waste requires laboratory and field investigations to evaluate migration parameters such as diffusion and dispersion coefficient of radionuclides in order to assess the site suitability for locating a high level radioactive waste repository. However, migration of radionuclides through the rock mass away from the radioactive waste repository is an extremely slow p...

In a headwater catchment in the Oregon Coast Range, we find that solid-phase mass losses due to chemical weathering are equivalent in the bedrock and the soil. However, the long-term rate of mass loss per unit volume of parent rock is greater in the soil than in the rock. We attribute this finding to the effects of biotic processes in the soil and to hydrologic conditions that maximize contact ...
