The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of ... Per saperne di più
In underground mining operations, the mined-out spaces (called stopes) need to be backfilled to maintain the stability of surrounding rock mass and increase the ore recovery. Cemented paste backfill (CPB), a mixture of water, binder, and tailings, has been intensively utilized in ... Per saperne di più
Standing column wells (SCW) are open-loop geoexchange systems used to provide space heating and cooling to buildings. As they use groundwater as heat carrier fluid and modify its thermo-chemical conditions along the year, they may favor calcite dissolution and precipitation, thus ... Per saperne di più
A similarity solution to Taylor's paint scraper problem for the flow of a non-Newtonian power-law fluid is presented. A shooting method numerical solution agrees with the results found for Newtonian fluids and is able to capture both shear-thinning and shear-thickening fluids. ... Per saperne di più
Ground freezing techniques using liquid nitrogen are commonly used in order to increase the mechanical properties of the soils. This article presents a new ground heat exchanger using aluminum to increase the effective radius of the heat exchanger. Simulation results indicate that the ... Per saperne di più
The Swedish Nuclear Fuel and Waste Management Company (SKB) operates the underground repository for low- and intermediate-level nuclear waste (SFR) located in Försmark, Sweden. An extension of the SFR is planned to accommodate mainly waste arising from the decommissioning of Swedish ... Per saperne di più
Some of the present metallic ores mines are located in areas formed by a heterogeneous fractured massif where groundwater flows preferentially through fractures. Underground mining in these zones can cause impacts in streams, lakes and change the natural water balance of the watersheds, ... Per saperne di più
Heap leaching in the mining industry had become a sophisticated practice at least 500 years ago. It is a mineral processing technology whereby piles of crushed Run-of–Mine rock are leached with chemical solutions to extract minerals. The goal of this work is to contribute to the ...

We deal with a problem of bentonite behavior during the saturation process in a high level waste repository of KBS-3V conception, SKB (2010). Bentonite is a type of clay with specific nonlinear behavior caused by water adsorption and swelling ability in contact with water. We solve ... Per saperne di più
We examine the poroelastics mode, which couples hydraulics and mechanics by some basic benchmarks. For cases with analytical solutions we check the accuracy for changing meshes and calculate the convergence rate. Per saperne di più
