 Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required 
Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts.The material of choice for shaft lining is mass concrete which is poured behind Shaft Forms in Lifts of 6m as the shaft advances (gets deeper).Shotcrete, fibrecrete, brick, cast iron tubing, precast concrete segments have all been used at one time or another.
