Abstract：The mismatch betweentheruningspeed of mining scraperconveyorandthecoalflow rateat the working face isoneofthemainreasonsforthelowoperating eficiencyof theequipmentandthewasteofenergyconsumption.Onthis basis， amethodofscraperconveyorrunningspeedcontrolbasedondigitaltwintechnologyisproposed，arunningspeedcontrol frameworkcomposedofactualscraperconveyor，digital twinmodelof scraperconveyor，twindataandspeedcontrolstrategyis designed，theworkingconditionofscraperconveyorisestablishedandresearchedbycombiningwiththebidirectionalcoal cutingprocessforcoal mining，whichcansimulatetherunning stateofseraperconveyorinrealtime.Therunning speedand variablespeed timeofthescraperconveyorcanberegulatedinteligentlyaccordingtothepredictedload，soastorealizethe intellgentcontrolof thescraperconveyor.Theexperimentalcomparisonwasconductedwiththedatacolectedfrom43101 comprehensiveminingfaceofYujialiangcoalmine.Theresultsshowthat，incomparisonwiththetraditionalfixed-speedcontrol， the method of scraperconveyor speed control basedondigitaltwin technologycanimprovetheloadingrateof scraperconveyor by 18.5% and reduce energy consumption by 10.83%
