Global Mining Review,
At Navoi Mining and Metallurgical Company (NMMC), cost optimisation remains a core operational priority. As part of this strategy, high-capacity conveyor systems are extensively deployed for the transportation of mined rock mass to permanent and temporary storage facilities.
Across NMMC’s open-pit operations and hydrometallurgical processing plants, belt conveyor systems have demonstrated their effectiveness as a reliable, energy-efficient, and economically advantageous method of rock mass handling. To date, conveyor lines with a cumulative length of 54.3 km are in operation. These systems facilitate the monthly transportation of more than 3.1 million m3 of rock mass.
The implementation of conveyor-based haulage significantly reduces cycle times, haulage distances, and operating costs associated with truck transportation, particularly fuel and lubricant consumption, fleet maintenance, and equipment wear. This contributes not only to lower unit production costs but also to improved operational efficiency and reduced environmental impact.
In recent years, NMMC has prioritised the development and expansion of high-productivity conveyor infrastructure, including the implementation of continuous cyclic-flow technology (CFT) complexes. In 2025 alone, new conveyor lines with a total length of 6356 m were constructed and commissioned, including 4900 m at the Muruntau open pit and 1456 m at the Daugyztau deposit. In 2026, construction is ongoing on additional conveyor systems exceeding 12.8 km in total length at the Muruntau and Auminzo-Amantoy deposits.
Importantly, all design, manufacturing, and installation works are carried out in-house. Under the localisation program, conveyor equipment is manufactured by the Navoi Machine-Building Plant and the Zarafshan Repair and Mechanical Plant, while construction and installation activities are performed by the Zarafshan Construction Department. This vertically integrated approach enhances operational control, strengthens industrial capacity, and supports sustainable cost reduction.
