More than a decade since the last gold brick was poured at Giant Mine, the boast of Yellowknife being a city where the streets are paved with gold carries the echo of a dream turned dark.
Barely a week goes by without a reminder of the mine’s most indelible legacy: a lunar landscape of gaping pits, toxic ponds andtons of arsenic tri. SOMBA K'E/YELLOWKNIFE Diavik Diamond Mines Inc. has entered into a partnership agreement with Det'on Cho Logistics to provide twice-weekly passenger service between Edmonton and the Diavik mine site about km northeast of Yellowknife, in partnership with Summit Air and First Air.

Following four years of construction, a new open-pit to access a diamondiferous kimberlite pipe (A21 Pipe), was officially opened at the Diavik Diamond Mine on Aug The site is located. the mine site is that were designed and constructed by the authors of the book.
The design differences between the bioreactors of continuous and periodic type are discussed. pseudo static. and impoundments. Stability concerns are raised in part by the use of tailings material in tailings dams/embankments; to mitigate these concerns, such embankments often rely on a certain amount of controlled seepage to enhance stability, which in turn affects.
The site covers square kilometers and contains a dormitory complex, a dining area, recreational and education facilities, an office and maintenance building, a warehouse, and an enclosed maintenance facility where even the largest hauling trucks used at the mine can be worked on year-round.

The area is characterized by low relief (less than 15m), a poorly developed drainage pattern, numerous shallow lakes and cold permafrost.
The mine is only accessible by aircraft during the. Slope stability in strong rock (>25 MPa based on classification from Hungr et al., ) is dominantly controlled by the presence, orientation, and geomechanical properties of discontinuities (Terzaghi, ).The three simplest structurally controlled failure mechanisms are also the most commonly assessed in rock masses: planar sliding (Figure (a)), wedge sliding (Figure (b)), and.
Based on laboratory tests, it is found that bottom ash possess the required filter ability, internal stability, drainage capacity, self healing properties and does not segregate. Accordingly, bottom ash has been adopted as an alternate filter material in internal drainage system of dyke embankments of various plants of NTPC.

Site preparation and clearing If a mine site is located in a remote, undeveloped area, the project proponent may need to begin by clearing land for the construction of staging areas that would house project personnel and equipment. Even before any land is mined, activities associated with site.
A lake ecosystem was severely affected by past arsenic contamination from a gold mine near Yellowknife, according to a new collaborative study undertaken by. to site exposure to wave action and soil stability analysis.

SECTION 3 STABILITY OF WASTE ROCK EMBANKMENTS CHAPTER 29 Site Selection, Characterization, and Assessment Placement of tailings by hydraulic means does not provide Another major area of concern. The 4-km-long dyke embankment was completed during the third week of October, just days before a site visit by The Miner and more than 50 analysts and bankers.
About 6 million tonnes of crushed rock were placed along the dyke’s path, which extends from the shores of Lac de Gras and encloses the A South and North pipes (only metres apart). What is the most prominent mine in the Yellowknife area.
What is its current status. Cominco, Ltd., the large British Columbia base-metal company, also hit it rich with the discovery of gold on the west side of Yellowknife Bay. After the amalgamation of some other claim blocks, the Con mine was built and brought into production in to work the veins on the Figure Yellowknife, NWT tel: () fax: () proud member of the Yellowknife Chamber of Commerce.

Geotextiles are those fabrics used in geotechnical applications, such as road and railway embankments, earth dykes and coastal protection structures, designed to perform one or more basic functions such as filtration, drainage, separation of soil layers, reinforcement or stabilisation.
recharging the water table and sand mining causes sinking of water tables in the nearby areas, drops leaving the drinking water wells on the embankments of these rivers dry. Turbidity increases at the mining site. Saline water intrusion takes along the coastal aquifers.
