Volume 14 • Issue 4 | 2017 | ASIA Miner | 49 Product News BUILDING on the solid legacy of the MD6420C, the new Cat ® MD6310 blasthole drill offers substantial technology, efficiency and productivity improvements. A key advantage of the machine, Cat electronics deliver advanced troubleshooting for efficient drill opera- tion and scalable automation. The building blocks include drill assist, semi-autonomous and re- mote control operation, and machine health reporting to improve drilling accuracy, reduce fuel consumption and lower total cost of ownership. Ideal for 12 and 15 metre bench heights, the MD6310 is appli- cation-built for efficient single pass drilling down to 13.7 metres or 17.5 metres, depending on mast configuration. Offering up to 30-degree angle holes for cast blasting, it is ideal for numerous mining applications. Reaching deeper hole depths, the MD6310 better matches spe- cific drill and blast requirements when working with electric rope shovels or other loading tools that require a tall and steep muck pile. Standard is a drill depth indicator, auto level/retract and auto mast, all of which contribute to efficient cycle times. Cat Command for drilling leverages remote and autonomous drill operation and serves as the off-board technology foundation of the drill. Scalable solutions allow customers to select the pre- cise level of drilling automation to match operating needs. The Drill Assist option executes all major functions for single pass drilling. Drill Assist automatically adapts and adjusts drill power to match ground conditions, which streamlines the drill cycle and lengthens bit life. Cat Terrain for drilling guides the drill for up to four times great- er pattern accuracy to ensure every hole is accurately placed and drilled to plan. The Terrain logging function ensures all production is timed, mapped and recorded, and the HP GPS navigation ensures accurate hole placement, proper hole depth calculated and adjust- ed based on altitude, and proper hole angle through orienting the drill heading and position. The MD6310 offers semi- autonomous drilling of single row mis- sions and remote control operation for remote operation missions. O ne remote operator station allows an operator to manage opera- tions and run up to three machines simultaneously. ONE of the world's richest underground copper deposits will be accessed with the help of high-capacity gearless driven conveyors from thyssenkrupp. The Industrial Solutions business area has won a contract to supply a material handling system for the new Oyu Tolgoi (OT) underground mine in Mongolia. The contract value is in the higher double-digit million euro range. thyssenkrupp will supply nine conveyors with a combined length of 9.5km as well as seven transfer towers operating at an hourly design tonnage of 7100 tons. First production from underground is expected in 2020. The OT mine complex is a joint venture between the Government of Mon- golia and Turquoise Hill Resources, which is majority-owned by Rio Tinto. From a depth of nearly 1400 metres beneath the Gobi Desert, the new underground material handling system is planned to transport 95,000 tons per day of copper ore to the surface. The main com- ponents are four high lift conveyors each equipped with 1.6 metre wide steel cord belts and dual 5500 kW gearless drives from Sie- mens. Further conveyors will feed the main incline conveyors and tie the new underground system into the existing process facility. thyssenkrupp Industrial Solutions' Mining Technologies business unit CEO Torsten Gerlach said, "This order again proves that thys- senkrupp is a strong player in the mining and materials handling industry. We are proud to contribute to this project with our intelli- gent belt conveyor technology and our strong global project execu- tion capabilities. The system will help the OT mine set standards in terms of productivity and safety." The mine began producing copper concentrate from an open pit operation in 2013. The future underground construction activities will transform OT into one of the most significant copper mines glob- ally. The order given to thyssenkrupp includes the engineering, design and supply of the new material handling system as well as required site support services during the construction and commissioning phases. It will be designed with an emphasis on ease of mainte- nance. This includes the ability to quickly replace chute sections as well as idler rolls and belt cleaners. The drive components are massive and great attention will be paid to safely transporting them underground and ensuring they can be safely exchanged. Overhead bridge cranes will be strategically lo- cated to not only service the equipment, but also to aid in erection of the major structures.
