tailings impoundments. A generic facility representative of those in Saskatchewan is: o Tailings deposited by wet mass dis-charge behind an embankment with two horizontal to one vertical side-slopes, a central core of glacial till, drains, an upstream shell of compacted tailings sands, and a downstream shell of sand and gravel.

unoxidized tailings, was installed below each cover to measure both the quantity and quality of percolated water. Six columns were installed in the laboratory to simulate soil-covered and uncovered tailings. The soil cover consisted of a 30 cm thick clay layer placed between two sand layers, each 15 cm thick. The soils were similar to those used in. The first book of its kind, providing over thirty real-life case studies of ground improvement projects selected by the worlds top experts in ground improvement from around the globe. Volume 3 of the highly regarded Elsevier Geo-engineering book series coordinated by the Series Editor: Professor John A Hudson FREng.
Pyrite was mixed in the simulated soils, which were prepared using sand and clay in conformity to the soil texture and the physical properties of the topsoil in the mine site, aiming at setting the sulfur content as from 0 to 30% by weight on the basis of the result of XRF by: 1.

Continued studies of soil improvement and revegetation of tailings sand slopes. Author(s) / Creator(s) Rowell, M.J.
Studies were continued in into the improvement of a five year old revegetated area on a tailings sand dike by the implementation of different fertilizer by: 1. Get this from a library. Continued studies of soil improvement and revegetation of tailings sand slopes. [Michael J Rowell; Syncrude Canada Ltd.] -- Describes the effect of differing fertilizer programs on revegetation of tailings sand dykes.
Nitrogen, phosphorus, and potassium should be added twice a year, but sulfur fertilizer is unnecessary. Revegetation of tailings sand without a soil cover in the Alberta oil sands J. Woosaree and B. Anderson | Mine ClosureBrisbane, Australia is generally used to mitigate poor water retention in the sand, but rather than using stockpiled cover soil in the establishment of the temporary cover, an alternative amendment was : J Woosaree, HB Anderson.
Abstract: Reclamation in the oil sands in Alberta is a high priority and can be challenging. Suncor Energy is in the process of reclaiming one of its consolidated tailings (CT) ponds (Pond 5). The CT is being capped with a layer of petroleum coke to accelerate the creation of a trafficable surface, and then with tailings : J Woosaree, HB Anderson.
The most critical step in phytocapping is the developing of the first vegetative cover because of the biotoxicity of the mine soil and mine tailings. Table of contents. Abstract Liquefaction of foundation soils imposes geotechnical hazards primarily in the form of loss of bearing capacity and permanent ground deformations.
Foundations in liquefiable soils need to be designed to withstand these hazards, or ground improvement measures need to be implemented to mitigate the resulting impacts. actual mechanical properties of the soil to be used in the tailings dam.
Considering the prominent ore to be excavated from the mine will be copper and molybdenum, estimations of copper tailings will be used.
Approximations for the material properties will be made from previous research on copper mine tailings conducted by Bhanbhro ().File Size: 1MB. streams around mining areas. There is an urgent need to reduce erosion of the slopes of mine tailings in-order to limit further devastation of natural ecology.
The present study investigates the possible use of cement to reduce erosion of the slopes of mine tailings dams. The pinhole erosion test was used to measure erodibility of tailings. REVEGETATION In an experimental programme of revegetation plots was established on the tailings area.
The successful stabilization of mine tailings with vegetation was the first step in developing new ecosystems. These systems were designed and developed to complement, as far as possible, the stage of development of theFile Size: 5MB.
ICMM and its members are committed to driving safety and environmental improvements through the mining industry.
After the tragic failure of the Samarco tailings dam, ICMM consulted with its member companies to determine how best to minimise the risk of a recurrence of such a catastrophic dam failure.
Tailings, waste products of the ore-dressing processes, are usually stored in a slurry form and pumped into sedimentation pond which is surrounded by natural heights and/or artificial walls.
The database of International Commission of Large Dams and United Nations Environment Programme showed that several hundreds of tailings dam have failed since Cited by: CASE STUDY: Direct Revegetation of Tailings Storage Facility at Kidston Gold Mine, QLD 49 FUTURE DIRECTIONS 51 Improved tailings disposal 51 CASE STUDY: Central Thickened Discharge at Sunrise Dam Gold Mine, WA 55 CASE STUDY: In-Pit Tailings Storage at Granites Gold Mine, NT 61 Improved final tailings landform On slopes steeper than 30 °, no soil depths are measured.
3) Finally, those areas with severe soil limiting factors preventing intensive land use were indicated on the maps. Soil limiting factors taken into consideration where stoniness, occasional flooding. Critical gradients for tailings dam design I.
Jantzer Luleå University of Technology, Sweden S. Knutsson Luleå University of Technology, Sweden Abstract Knowledge on tailings dams design is often derived from conventional earth and rock fill dams that are designed for relatively short service periods.
Historic tailings discharge data is run through the beach shape model, and the shapes predicted by the model are compared with aerial survey data of a real tailings stack for validation of the shape model. This work not only presents a new method of tailings stack shape prediction, but also a plausible theory for explaining the.

Mclver Partner Casagrande Consultants Arlington Mass. ABSTRACT Similarities are noted in the practices and problems of constructing dams to impound mine tailings fly ash and chemical. Accompanying the modernization program are routine efforts to improve environmental performance in many areas, such as employee and community education, hazard elimination (e.g., elimination of underground storage tanks and polychlorinated biphenyl compounds), substitution of environmentally sound products (e.g., detergents for chlorinated.
Growth of soil algae and cyanobacteria on gold mine tailings material. The goal of revegetation of gold mine tailings storage facilities is to reduce aeolian pollution, nutrient leaching and erosion caused by exposure to wind and water.

The detrimental impact of mining has been a topic of concern for many years. Abandoned mine tailings from a wide variety of industries are found around the world. The chemical composition of tailings depends on the minerals mined and the extraction technique.
For example, cyanide compounds have been used in some gold (Au) by: A new study suggests new guidelines in order to mitigate the earthquake risk triggered by hydraulic fracturing. Practical Soil Dynamics. The objective of this book is to fill some of the gaps in the existing engineering codes and standards related to soil dynamics, concerning issues in earthquake engineering and ground vibrations, by.control, visual improvement and removal of threats to human beings (Wong, ).
Reclamation strategies must address soil structure, soil fertility, microbe populations, top soil management and nutrient cycling in order to return the land as closely as possible to its pristine condition and continue as a self-sustaining ecosystem.
