Канадская компания Mandalay Resources гордится созданием высокой биржевой стоимости акций за счет приобретения недооцененных активов, которые могут: стать быстро окупаемыми, разведываться при самофинансировании, устанавливать и поддерживать высокие показатели операционной маржи и вернуть денежные средства акционерам.
As current owner and operator of the Costerfield gold-antimony mine, Mandalay used RCT’s Smart Technology to help deliver value at its site in Victoria, Australia.
The Costerfield mine has a "narrow vein operation” so it is critical that the drives are kept to a minimum width to minimise ore dilution for ore processing efficiency. However, this made reaching the ore in some areas of the mine quite difficult.
In addition, the site’s drilling and blasting practices aimed to maximise recovery by throwing the ore towards the draw point, however this only enabled a 75 per cent ore recovery to be achieved. The remaining 25 per cent of the ore within the stope void was out of safe reach of the loader under manual operation as the loader’s operator cab was not permitted to go past the brow of the stope.
Для выемки руды, оставленной в слепых восходящих выработках, на проекте применяли погрузчик с дистанционным управлением.
RCT’s Guidance simulator was used to review Costerfield’s mine site plan layout on several of its drives. It was upon reviewing this footage that several critical, tight areas within the drives that had previously been scaled back were in fact accessible with machines equipped with RCT Smart Technology.
Impressed with this verification, Mandalay chose to install RCT’s ControlMaster® Guidance and Teleremote systems to its Sandvik LH203 which would substantially increase ore recovery.
Помимо доступа в труднодоступные места шахты, при управлении погрузчиком с помощью систем автоматизированного и дистанционного управления RCT стал также возможен безопасный доступ к большей части руды, которая оставалась в очистной выработке после буро-взрывных работ.
Оператор может управлять погрузчиком из безопасной подземной станции управления производства RCT.
Implementing RCT’s ControlMaster® Guidance and Teleremote systems on the loader allowed operators to successfully navigate the previously inaccessible narrow drives with ease, all while avoiding contact with the walls; eliminating machine damage.
The operators’ ability to switch from Guidance to Teleremote mode to load the once unattainable ore in the bucket from the stope, helped to increase production substantially.
В дополнение к минимизации повреждений техники и повышению производительности эти системы способствуют более безопасному ведению добычи. Операторы теперь могут управлять погрузчиком из комфортной и безопасной станции управления, размещенной в укрепленном грунте.
Внедрение систем автоматизированного и дистанционного управления на руднике Костерфилд позволило увеличить долю извлекаемой руды до 95 процентов в слепых забоях.
It was Mandalay’s first project with RCT, but not its last. Following on from the overall success of the project the client has decided to progress with a second full Teleremote and Guidance systems to be installed onto a second loader, along with a second new operating station.
Поставка второго модуля запланирована на начало июля 2016 года.
RCT Account Manager Geoff Steele said both site management and production people were extremely pleased with the results.
"The loader can access the stope areas very successfully under Teleremote and Guidance systems, apart from improving ore recovery from previously inaccessible areas, Mandalay is pleased to give our staff the opportunity to learn new skills of operating Teleremote loaders, in the air conditioned environment of the Teleremote Operator Cabin. This improves safety outcomes for our loader operators because the Sandvik LH203 loaders are currently open cabin loaders.”
