The invention relates to carrying type comprehensive mechanized roadway temporary supporting equipment and an application thereof. The carrying type comprehensive mechanized roadway temporary supporting equipment includes a heading machine, a retractable transfer system and a temporary supporting mechanism; the retractable transfer system is arranged on the heading machine, the temporary supporting mechanism is placed on the retractable transfer system, and the temporary supporting mechanism is transferred by the retractable transfer system to an unsupported region at the front of the headingmachine. According to the carrying type comprehensive mechanized roadway temporary supporting equipment, the design mode of separating the temporary supporting mechanism and the heading machine is adopted, by using the retractable transfer system of the heading machine, the temporary supporting mechanism carried by the heading machine is transferred to the unsupported region of a roadway operationface; through the extending movement of an piston rod of a hydraulic cylinder X, a supporting plate leaves a bracket to connect to a top plate of a roadway; and through setting the oil pressure of the hydraulic cylinder X to exert an initial support force to the top plate, the temporary supporting is completed, the heading machine is retreated from the region of the temporary supporting mechanism, and anchor protection operation can be conducted by workers in a safety region established on the bottom part of the temporary supporting mechanism.
