A combined support suitable for advanced support of a roadway comprises a plurality of metal friction props, a hydraulic prop, a top steel cap and a bottom steel seat. The metal friction props and the hydraulic prop are fixedly connected between the top steel cap and the bottom steel seat, the hydraulic prop is located in the middle, the metal friction props are uniformly distributed around the hydraulic prop, and the metal friction props are matched to limit the telescopic height through a metal pin. The combined support suitable for advanced support of the roadway can support a roof timely and actively, and has the characteristics of fast resistance increasing, large work resistance, stable load carrying capacity, and contraction performance; the combined support combines the advantages of the metal friction props and a single hydraulic prop, the bending resistance is high, and the problem that a compression bar is unstable when a single prop supports the roof is avoided; and the combined support also has the advantages of being low in cost, convenient to machine, high in adaptability to geological conditions, easy and convenient to use and maintain, flexible in operation, and the like.
