 \nSINOPSIS  \n# INTRODUCTION\n\nOriginally it was intended thatmining of President Steyn's south-eastern section of the lease areawould be carried out from a sub-shaft system as an extension to theexisting No.3 shaft system,whichprovides access to the ground abovethe 1830m level.Re-assessment ofthe potential of the area followingpromising borehole results to thesouth showed the need for revisionof the shaft requirements of bothPresident Steyn and PresidentBrand.New planning required thePresident Steyn No.3 shaft to behanded over to President Brand sothat the latter could exploit theirsouthern area,and the replacementof President Steyn No.3 shaft by anew No.4 shaft system to a depthof 2300 m sited as shown in Fig.1.The new shaft not only replaces No.3 shaft but allows an increase inproduction.  \nThe economics of several shaftsystems ranging from main and sub-vertical shafts to twin vertical mainand ventilation shafts were exam-ined,and finally a large single-liftshaft,divided by a brattice wall forventilation purposes,was selected aspresenting the most economical sol-  \n# Design features of a deep-level shaft\n\nDesign and technical features of a large,deep shaft are described,and details of the sinking equipment are given.Special features in shaft steelwork,materials handling,and station layouts are described and illustrated.  \nThe details of the precast brattice wall are given,together with the reasons for the separation of all steelworkfrom the brattice wall.  \nA newly developed device for the location of the shaft conveyances while loading or unloading at undergroundstations is briefly described and illustrated.  \nThe paper concludes with a summary showing the rates of progress and costs for the shaft-sinking operation.  \nDie

the winding plant al-ready in the mine's possession andthe winding ropes that could beaccommodated.The main collectinglevel will be at 2234 m(73 level),the upper working level at 1759m(58 level),and five levels betweenthese horizons together with thenecessary service levels as shown inthe diagrammatic section of Fig.2.  \nThe capacities required of theshaft are as follows:  \nTons hoisted per month—246000Ventilation—528 m³/s at 7,72kPaMen,daily—approx.7300 personsMaterial,daily—approx.340 cars.  \nWhile the tonnage to be hoistedand the ventilation capacities setthe main parameters of the shaft,thetransport of men and material re-ceived careful consideration becausethese aspects have caused problemsin older shafts.To meet the capaci-ties,four skip compartments andfour men and material compartmentsare necessary.The configurationarrived at is shown in Fig.3.  \nThe main particulars of the shaftare as follows:  \nTotal depth from collar—2365mDepth of wind—2315m  \nby
