  • Simulation of Three-Dimensional Pore-Pressure Distribution for Slope-Stability Analysis

    Abstract: A 3D groundwater flow model was constructed using MINEDW [1] to simulate pore pressure at the Chuquicamata open pit mine slope in Chile. Three main factors required the implementation of a 3D model for the prediction of pore pressures: (1) discrete zones of recharge in the gravel zone lead to the non-uniform flow field; (2) the low-permeability west fault and shear zones maintain ...

  • Lövön Sweden Project - Case Study

    The embankment dam at Lövön was built between 1972 and 1973 and has a total length of 1500m, and a height of 25m. Leakage water cannot be collected and measured by conventional leakage systems, due to a high downstream water level. Two optical fibre loops were installed in 1998 to measure the temperature upstream, above and downstream from the core. The optical fibres are ...

  • The feasibility of non-water reaction polymer grouting technology application in seepage prevention for tailings reservoirs

    Tailings reservoirs generally consist of a tailings dam, a tailings conveying system and a drainage system, which are indispensable facilities and provide security and environmental protection for storing tailings and clarifying water in some industries (e.g., metallurgy, non-ferrous building materials, nuclear and chemical industries). Consequently, consolidating seepage prevention and ...

  • Tracing groundwater recharge sources beneath a reservoir on a mountain-front plain using hydrochemistry and stable isotopes

    Mountain-front recharge, including mountain block recharge and stream seepage, is important for basin aquifers. With the construction of reservoirs in mountainous areas and the recurrent seepage problems of dams, reservoir seepage might become another type of mountain-front recharge. This study identified the recharge sources of groundwater beneath Huangbizhuang Reservoir on the North China ...

  • A cost model with several hydraulic constraints for optimizing in practice a trapezoidal cross section

    Open channel structures are essential to infrastructure networks and expensive to manufacture. Optimizing the design of channel structures can reduce the total cost of a channel's length, including costs of lining, earthwork, and water lost through seepage and evaporation. The present research aims to present various optimization models towards the design of trapezoidal channel cross section. ...

  • Investigating the permeability of fractured rock masses and the origin of water in a mine tunnel in Shandong Province, China

    The coastal Sanshandao mine is threatened by the overlying Quaternary water and seawater. Following an introduction to the geology and hydrogeological conditions in the mine area, a detailed hydrogeological survey and sampling were conducted and hydrochemical and stable isotopic (δ2H and δ18O) tests on various waters were carried out to characterize the origin of water in the mine ...

  • Relations between groundwater flow in an unconfined aquifer and seepage patterns in a closed-basin lake in glacial terrain

    Groundwater dynamics affect lake water budgets, but its major factors and mechanisms still need clarification. This study evaluates the effects of surrounding groundwater flow on seepage direction and assesses factors that affect seepage flux in a closed-basin lake in northeastern Estonia – Lake Martiska. A piezometric map was used to determine directions of groundwater flow around the ...

  • Open Pit Modeling

    The Problem Open pits are a common method of mining in the world. The design of such pits requires the application of technologies from a number of fields. One of the common scenarios is that the bottom of the pit may possibly extend beneath the water table of the surrounding geo-strata. If this is the case then a suitable set of pumping wells must be designed in order to ensure that ...
