Posedand importante resurse minerale exploatabile, pana nu demult economia comunei era sustinuta de activitatile miniere legate de exploatarea carbunelui brun si a agregatelor de balastiera cantonate in luncile Somesului, Almasului si Braglezului. in ultimii ani, pe langa sectorul agricol bine reprezentat la nivelul comunei, s-a produs o revigorare accentuata a sectorului economic secundar si in randul serviciilor.
Din punct de vedere turistic, fara indoiala Somesul reprezinta principalul element atractiv al comunei. Fondul turistic de natura antropica, reprezentat de ruinele castrului roman de la Tihau, biserica de lemn "Sfintii Arhangheli" din Turbuta (sec. XVII), castelul Josika din Surduc (sec. XVII-XIX) completeaza zestrea turistica a comunei.
