Uralkali completes construction of skip shaft tubbing column at Ust-Yayva mine

Uralkali (LSE: URKA; the Company), one of the world’s leading potash producers, has completed the construction of a 273-metre high tubbing column at skip shaft No. 1. The tubbing column is designed to bring sylvinite ore to the surface and is part of the continuing development of the Ust-Yayvinsky block of the Verkhnekamskoye deposit.

The column comprises 182 cast iron rings. The tubbing lining is necessary to minimise the impact of the rock pressure and to ensure the safe operation of the shaft in the event of contact with water-bearing layers.

Sinking operations will continue down to 467 metres. The completion of shaft No.1 construction is planned for 2017.

Sinking operations are also in progress for cage shaft No.2, which is designed to transfer people and cargo. 372 metres of the shaft has already been sunk and the installation of the tubbing lining will begin soon. The completion of construction is planned for 2017.

The construction of the hoist-engine house, step-down power substation, and administration and housing building has begun at the Ust-Yayva production site. Foundation works are in progress for a 6.3-kilometre conveyor belt to transport potash ore to the Berezniki-3 plant.

About the project

The project to develop the Ust-Yayvinsky block of the Verkhnekamskoye deposit includes the construction of a new mine with two mine shafts with an annual capacity of 2.5 million tonnes of potassium chloride. In December 2011, Uralkali signed a contract with Deilmann-Haniel Schachtostroj for the construction of the shafts at the Ust-Yayvinsky mine. The contract includes the development of working documentation, construction of temporary structures for the surface tunnelling system, shaft sinking and the development of infrastructure for utilities. The sinking of shaft No.1 started in 2013. The mine will produce the first ore in 2020 and will enable Uralkali to replace the depleting ore reserves of the Berezniki-2 mine.

Uralkali (www.uralkali.com) is one of the world’s largest potash producers and exporters. The Company’s assets consist of 5 mines and 7 ore-treatment mills situated in the towns of Berezniki and Solikamsk (Perm Region, Russia). Uralkali employs ca.11,000 people (in the main production unit). Uralkali’s shares and GDRs are traded on the Moscow Exchange and London Stock Exchange, respectively.
