Quarry Academy seeks solutions for Qatari high volume construction projects
Wednesday, March 24th, 2010
A two day ‘Quarry Academy’ for key management in Qatar was recently staged to discuss blasting and crushing solutions to meet demand for the large volume projects forecast for the Gulf Kingdom.
The ‘Academy’, jointly sponsored by local distributors Q-FAB and Boodai, was attended by almost 40 key senior management representing Qatari contractor, quarry operators and drill and blast companies.
“The ‘Academy’ was a continuous lecture-style presentation on the quarry process,” said Jukka Naapuri, General Manager, Sandvik Middle East FZE.
“As such, there were just two key papers – the first covering everything from opening the quarry up to feeding rock to the crushing plant . The second described in detail the crushing process and introduced the concept of mobile crushers.”
Upcoming projects such as, for example, the new Doha Port, specifying the movement of more than 50 million m3, have not been undertaken before in Qatar and are therefore expected to pose problems for local and international contractors alike.
Blasting, for example, in terms of the high volumes and how it can be handled by the authorities was just one key topic of discussion.
Solutions were also presented in introducing blasting techniques with 4½ inch diameter holes and Sandvik hydraulic top hammer drill rigs for the first time in Qatar.
Crushing solutions involving the removal and processing high volumes of aggregates, sand and gravel including reuse on the project and stockpiling were also discussed in detail.
In meeting the challenges posed by these high volume projects, emphasis on new crusher technology and techniques with mobile, jaw, impactors and screens, were also analysed with the presentation of new mobile impactors, heavy scalping screens and mobile jaw crushers from Sandvik.
The ‘Academy’ is seen as a training programme focussing on the excavation process and mutual interdependencies of its various sub processes. It emphasises optimisation of the entire excavation process, not simply patchwork measures aimed at individual areas of operation.
Besides sharing knowledge about quarrying for the production of crushed stone products, the lessons Quarry Academy teaches can also be applied to a wide range of excavation operations used in other types of construction projects such as building roads, railways, and electric power plants.
To date, almost 1000 people representing excavation companies from around the world have participated in this unique and useful training program.
“It was seen as a huge success particularly because it was attended by all the decision makers in the region,” said Jukka, adding, “The feedback for this, the first academy of its type in Qatar, was extremely positive.”
On completion of the ‘Academy’ in Doha, participants were presented with a certificate.
