• A major gold producer had identified a site in the Andes at an altitude of 3900 m where gold was found in large quantity. However to access the ore body it was necessary to dredge a bog completely and transport water, gravel, silt and chopped up grass to a water storage pond at a higher altitude. The owner hired a geotechnical expert to conduct a feasibility study. The study initially focused on the top layers that consisted of grass, water and about 10% silt but then extrapolated to the bottom layers that contained sand and gravel up to 20 mm in diameter. The study had proposed to use 8 hydraulic excavators that were deemed very dangerous in the bog, and therefore required highly trained operators who could swim out of the bog. The 8 excavators were connected by hoses to a common pipeline to a sump on the shore feeding three pumps in series. The geotechnical consultant had assumed that the dredged material could be transported at the weight concentration of 40% while the submersible pumps typically dredged at the maximum weight concentration of 30%. ORC provided peer review but indicated that the lower layers of the bog would require more pumping power as well as operation at higher velocity than the top layers due to a much coarser particle size distribution. ORC also expressed some concern that the hydraulic excavators had experienced in some other sites accidents tipping off and leading to accidental death of an operator. The peer review recommended using an air cushion platform that exerts a minimum pressure of 1 psi to navigate the bog. This also would have allowed the use two larger hydraulic driven submersibles to reduce the number of operators, hoses to the pipeline. An air cushion dredging platform was identified in Singapore for lease as well as another one in Vancouver, British Columbia. The peer review also recommended an increase of the number of booster pumps to four in series to handle the gravel at the deepest layers. The peer reviewer also identified the risk of formation of balls of clay with chopped grass that clog the pipeline in certain points and proposed a number of solutions such as proper design of booster pump station sump, discharge approach into the storage pond. The reviewer also recommended that the reclaim pumps in the storage pond be horizontal slurry pumps rather than vertical turbine pumps.Outcome: The peer review resulted in a series of recommendations for a more stable dredging and pumping system while proposing a safer technology to avoid accidents associated with hydraulic excavators. The proposed single air cushion platform with large excavator and two large submersible pumps is also likely to reduce the number of operators and auxiliary refueling vehicles for the system proposed by the Geotechnical consultant.
