Raw Coal Handling
Powell Construction Company performed all engineering, partial procurement, and installation for a new raw coal handling facility at the current site. Raw coal handling consisted of a new reclaim tunnel, stacking tube, stacking conveyor, reclaim conveyor, scalping screen, rotary breaker, and crusher.
Slope Conveyor/Building Upgrade
Powell performed all engineering, fabrication, partial procurement, and installation of additions and modifications to the existing slope conveyor and the transfer building. Additions and modifications were made to accommodate the new mining conditions provided by the owner. A large portion of this project was performed while the original slope conveyor was still in operation with the final phase and tie in completed under strict schedule constraints during a mine wide outage.
Preparation Plant Additions and Upgrades
Powell performed all engineering, fabrication, partial procurement, and installation for plant upgrades per the Owner’s modified flow sheet. Upgrades included an overall building addition, increasing the capacity of one circuit, addition of a 2nd circuit, and addition of a rewash circuit. PCC constructed the additions and upgrades while the owner maintained an operating facility. Tie-ins and additions were implemented during strategic shut-downs during the project.
Clean Coal Handling/Storage/Loadout Upgrades
Powell performed all engineering, fabrication, partial procurement, and installation for the clean coal system upgrades. Upgrades included modifications to the plant clean coal conveyor, modifications/additions to the clean coal transfer, upgrading the clean coal reclaim feeders, upgrade of the clean coal reclaim conveyor, modification of the existing train loadout (transformed to a transfer), addition of the clean coal loadout transfer conveyor, and addition of a train loadout facility. The train loadout facility was taken down from a different site, re-painted, transported, and re-installed at the new facility. All work was completed while the existing mine was in operation. Final tie-ins were completed during outages.
Refuse Handling Upgrades
Powell performed all engineering, fabrication, partial procurement, and installation for the refuse system upgrades. Upgrades/additions included modifications to plant refuse collection conveyor, new breaker refuse conveyor, relocated refuse transfer conveyor including several road/pond/creek crossings utilizing tube trusses, and new refuse transfer to stacking conveyor.
