TURKEY Antioch salvation of St. Peter’s Turkey’s iconic cave church gets rock bolt protection Mining & Construction – 1 / 2014

Above: The rescue team working for Turkish contractor Kuzey Dagcılık line up for a photo to commemorate the completion of their successful mission. Swellex to the rescue: These mountaineers had to abseil down the mountainside to reach the section of loose and crumbly rock that threatened to fall on the famous cave church of St. Peter’s. Atlas Copco’s Deyvi Akkris and Bahadir Ergener, Sales Engineer and Business Line Manager, instruct the team on how to install the Swellex Pm24. Right, the APSP 300 Swellex pump is hoisted into position. The Church of Saint Peter near the city of Antioch in...

Since its introduction in the 1980s, the Swellex rock bolting system has gained wide recognition in mining and tunnelling. This unique bolt is made of a welded tube folded on itself and sealed at one end. This enables a strong anchorage to be achieved through a combination of friction from radial pressure and mechanical interlocking from profile deformation. The bolts are expanded with high pressured water (300 bar). For St. Peter’s Church, 3  and m 3.6 m plastic coated Pm24 Swellex rock bolts were chosen. This model starts to elongate at a pressure of 20 t and is fully load bearing after...

Raiseborer stars in major tunnel project for Winter Games 2018 As the winter Olympics in Sochi came to its spectacular close, athletes and sports fans alike were already setting their sights on the next Olympian challenge – and so were the engineers and ventilation specialists at SungPoong Construction. he Winter Olympics 2018 are to be held in PyeongChang, South Korea, and a new super highway will enable the world’s sports fans to travel to and from the venue quickly and safely. One of the key elements of the project is the construction of the Inje Tunnel, which at 10.9 km long will be the...

An Olympian achievement: High above the Inje Tunnel in the mountains of Kangwondo, South Korea, the Robbins 73 RVF C raiseborer was used to bore two ventilation shafts, 212 m and 307 m in length, each with a diameter of 3.1 m, later to be...

China moving on… …from pneumatics to hydraulics In the ancient city of Suizhou, many things have stayed the same for thousands of years, but not the way the local drillers operate. These days, hydraulics is getting the better of pneumatics. Atlas Copco’s PowerROC T25 DC drill rig, made in Japan, is convincing Chinese customers of the wisdom of making the transition from pneumatic to hydraulically controlled equipment. he city of Suizhou in China’s northern province of Hubei, is well known as the hometown of the ancient Chinese emperors Yandi-Shennong and Huangi. It is also the home of...

Ituango Project Zone Medellin Bogotá Good Energy Colombia’s Future It’s been over 30 years since it was first planned, but once in operation, the Ituango hydroelectric plant will be the largest in Colombia, generating 2 400 MW or around 17 percent of the country’s energy needs. A large and diverse fleet of equipment, strengthened by onsite service maintenance and drill steel supply, is helping this project to finally become a reality. Mining & Construction – 1 / 2014

Heading up a world class fleet: The Atlas Copco three-boom drill rig, Boomer XE3 C, at work in the 240 m long powerhouse cavern where some 270 000 m 3 of rock is to be excavated. It is one of seven Boomer rigs being used on the project. hase I of the Ituango hydropower project consisted of preliminary construction work including an access road to the site, a river diversion and an access tunnel to the underground area. Phase II comprises the main civil engineering works being handled by CCC Ituango, a consortium formed by Brazil’s Camargo Correa and Colombian firms Constructora Conconcreto...

Taming the waters of the Cauca Canyon Rugged green peaks and stunning views in every direction. This is the first impression that hits any visitor to Colombia’s north-western Antioquia region where construction of the Ituango Hydroelectric Project is now in full swing. Colombia currently has 14 000 MW of installed electricity generating capacity and when it comes on stream in 2020, the new Ituango plant will add a further 2 400 MW to the grid. “This project is a huge responsibility for everyone involved and is expected to provide enough energy to meet the growth in demand for at least the...

On site: An XAS 375 portable compressor and (right) a QLT M10 lighting tower. excavation of approximately 270 000 m3. After passing through the turbines, the water will flow downstream to the surge chambers and then discharge into the Cauca River via four tailrace tunnels, two from each surge chamber about 1 400 m downstream from the intake site. New drilling fleet The new Atlas Copco fleet at Ituango includes seven Boomer drill rigs of various models with one, two or three-booms; 15 FlexiROC T35 drill rigs; four Diamec 262 (now Diamec U6) core drilling rigs, three Scooptram ST2G loaders;...
