February 02, 2011 Use of the Light Weight Deflectometer (LWD) at Highland Valley Copper Mine
Abstract:
The Light Weight Deflectometer (LWD) is a hand portable version of the falling weight deflectometer typically used for paved road evaluations. It is currently underutilized in North America, although it is gaining acceptance by several American state Departments of Transportation
February 02, 2011 Cyclic and Post-cyclic Laboratory Test Results on Undisturbed Samples of Filter Pressed Mine Tailings
Abstract:
Relatively little information is available regarding the cyclic behaviour of consolidated mine tailings. A major issue is that tailings often cannot be reliably classified based on conventional empirical techniques for sands or clays.
February 02, 2011 Evapotranspiration Dewatering Effect On CT Deposits By Grasses
Abstract:
Greenhouse experiments were conducted to assess the feasibility of using five grass species to dewater composite / consolidated tailings (CT) via evapotranspiration. Selected plant species were directly seeded via modified broadcast seeding, hydro-seeding with mulch, and
February 02, 2011 Ground Improvement by Dynamic Compaction at a Tailings Disposal Facility
Abstract:
This paper presents two case histories of ground improvement by dynamic compaction (DC) at the Myra Falls mine in Vancouver Island, British Columbia, Canada. Dynamic compaction was employed to densify soils at two sites within the operating mine: a waste rock dump beneath
February 02, 2011 Hidden Valley - Design and performance of the first tailings dam in highland Papua New Guinea
Abstract:
The Hidden Valley tailings storage facility (TSF) has set a precedent in environmental management of tailings in Papua New Guinea (PNG). Modern mining in PNG arguably began with the development of Bougainville Copper in the late 1960s, and continued through to Ok Tedi,
February 02, 2011 Jet grouting for the Highbury Interceptor Siphon access chamber
Abstract:
The Highbury Interceptor Siphon consists of three concrete pipes conveying sewage under the North Arm of the Fraser River from Vancouver to the Iona Island Wastewater Treatment Plant in Richmond, BC. The eastern pipe of the siphon was successfully lined with the Cured-In-Place-Pipe
February 02, 2011 Penstock Valve Seal Engineering and Upgrade at the City of Calgary’s Glenmore Dam
Abstract:
The City of Calgary’s Glenmore Dam has two 12 ft diameter penstock discharge of water (DOW) valves to control the water level of the Glenmore Reservoir. These valves and penstocks also allow water to flow to three turbine pumps, and to maintain water flows to the Elbow River.
February 02, 2011 Predicting Development of Undrained Shear Strength in Soft Oil Sands Tailings
Abstract:
This paper presents a methodology that can be used to make projections of the rate of development of undrained shear strength in a hydraulically placed oil sands tailings deposit. The predictions are based on the assumption that tailings pond will be managed in a manner
January 28, 2011 Characterizing Tailings to Better Predict Consolidation Behaviour During Desposition
Abstract
As part of the geotechnical design and water management, it is required to predict the settled density of tailings to both size the tailings storage facility and to determine the volume of water to be released from the tailings.
January 28, 2011 Identifying the Behavioural Characteristics of Clay Cliffs using Intensive Monitoring
Abstract
Coastal monitoring is routinely undertaken to provide an archival record of cliff-line movement that can be used in the development and validation of predictive coast retreat and evolution models. However, coastal monitoring is often purely quantitative in nature, and financial
October 03, 2009 Tunnels And Penstocks of The Nam Theun 2 Hydroelectric Project
AbstractThe 1,070 MW Nam Theun 2 Hydroelectric Project is located in central Lao PDR. The tunnels and penstocks convey the power flow from the reservoir impounded by the Nakai Dam, down to the surface powerhouse located at the base of the escarpment on the Nam Kathang River.
October 03, 2009 Mcgregor Reservoir Rehabilitation Project
Abstract:The Carseland-Bow River Headworks (CBRH) is a major multi-purpose water delivery system, located in southern Alberta, that supplies water from the Bow River to 87 000 ha of agricultural land and numerous municipalities .
September 18, 2009 Wetlands treatment of mine drainage from the Tucush Valley Waste Dump at the high altitude Antamina mine, Peru
Abstract:A new water treatment facility was constructed in 2005/2006 to manage drainage from the expanding Tucush Valley waste rock dump at Antamina Cu-Zn-Mo mine, located in the rugged high Andes in Peru, 4,200 m above sea level.
August 19, 2009 Geotechnical conditions and ice loading for an offshore drilling platform in the Canadian Beaufort Sea
AbstractThe SDC mobile arctic drilling platform was deployed 50 km offshore in a water depth of 14 m at the Paktoa site in the Canadian Beaufort Sea over the winter of 2005-2006. Geotechnical investigations were done from the landfast ice prior to deployment and from the SDC deck.
July 29, 2009 Zoned Strength Model for Oilsands Upstream Tailings Beaches
AbstractTailings dam design in the oilsands industry frequently uses upstream constructed dykes to contain ponds of fine tailings and water. These upstream dykes comprise compacted outer shells and un-compacted beaches of coarse tailings sand.
July 28, 2009 Three Year Construction Plan for Ultimate Configuration of Highland Valley Copper Tailings Storage Facility
Abstract:This paper describes the construction plan to complete construction of the Highland Tailings Storage Facility to either the Year 2019 Option or Year 2023 Option. The Highland Tailings Storage Facility is a conventional impoundment approximately 9.
July 22, 2009 Transition of a major tailings facility in a sensitive environment - from operation to decommissioning at Brenda Mine
AbstractBrenda Mine closure plan had been developed in consultation with regulators and stakeholders. Reclamation work at the mine was carried out whenever practical, while the mine was still in operation prior to 1990. Additional reclamation work continues to date.
