    Bridge removed in rehabilitation

    The rest of the areas will be returned to, as close as possible, the original state before mining began.

    Saturday morning saw the removal of the conveyor bridge leading from Twisdraai East to Twisdraai Export Plant near the old Twistdraai mine. The road between Charlie 5 and Greenfields were closed for traffic for most of the day. TW Civils & Earthmoving removed the conveyor bridge across the road. The bridge was part of the conveyor system that moved coal from Twisdraai East to Twisdraai Export Plant. Sasol mining is no longer using the shaft and has awarded TW Civils & Earthmoving the contract to rehabilitate the shaft complex and other areas of the old Twistdraai mine. Engineers estimated, after careful calculations, that the bridge should weigh approximately 30 to 35 tons. The base of the bridge was filled with concrete that added to the weight. When it was lifted the scale inside the crane gave the weighed it as 36 tons. A huge Liebherr mobile crane from Marlboro Crane Hire was used to lift the bridge. The crane has the capability to lift 400T and had 140-ton counterweights when it lifted the bridge. The bridge was safely placed next to the road for further dismantling. TW Civils had already done a lot of work on the rehabilitation of the Twistdraai complexes. The shafts at Twisdraai Central and Twistdraai East have already been demolished and also the redundant buildings. Twistdraai Central was demolished in February 2015 and Twistdraai East was demolished in September 2018. According to the info that the Bulletin received, a huge concrete pyramid will be erected over the area where the shaft was at Twistdraai East. The rest of the areas will be returned to, as close as possible, the original state before mining began.
