MINE HOISTS The 200 t/h (4,800 t/d) Vertical Conveyor System from FKC-Lakeshore at Fresnillo mine Frontier-Kemper set for Warrior Met Coal project Tutor Perini Corporation, a leading civil, building & construction company recently said that its subsidiary, Frontier-Kemper Constructors, has been awarded a contract valued at approximately $63.7 million by Warrior Met Coal BCE, LLC for the Blue Creek Energy Mine #1 project in Tuscaloosa County, Alabama. The scope of work includes the excavation and construction of the mine shaft, mine slope, slope hoist and service hoist. Frontier Kemper has extensive experience in hoist projects, which are mainly managed through subsidiary FKC-Lake Shore. FKC-Lake Shore also recently provided designbuild mine hoists with related appurtenances to Nevada Copper's Pumpkin Hollow Mine. FKC-Lake Shore was responsible for the design and fabrication of the service hoist, auxiliary hoist, controls and related conveyances. These hoisting systems will be used to transport personnel, equipment, and supplies underground in support of mining operations. A real hoisting innovation from FKC-Lake Shore came in 2016 when it was contracted to provide a new Vertical Conveyor System for the San Diego Shaft at Fresnillo PLC's Fresnillo mine. The mine, located in Zacatecas in central Mexico, specialises in the extraction of silver. The vertical belt is a FLEXOWELL ® S-shape system measuring 830 m in length. The Vertical Conveyor System handles 200 t/h at 400 m of lift; with the belts from Continental ContiTech. The system is still going strong after more than three years. FKC-Lakeshore says with this proven project it is now comfortable with depths far greater than the current largest installed depth of 400 m and that work is in the pipeline on these designs. Thyssen Schachtbau and Siemens cooperation in Belarus & Russia The first large components of two double drum production winders for Slavkaliy’s Nezhinsky potash mining complex in Belarus were recently completed by Thyssen Schachtbau subsidiary OLKO-Maschinentechnik GmbH.
