The invention relates to a temporary supporting forepoling bar suspension device of a full anchor-cable supporting roadway and application. The device is characterized in that the suspension device isin an inverted L shape and comprises a longitudinal plate and a transverse plate, an anchor device penetrating hole is formed in the transverse plate, a threaded hole is formed in the top of the longitudinal plate, and a safe baffle plate is arranged on the inner side of the transverse plate, and the length and width of the safe baffle plate are same as those of the transverse plate; according tothe device, each forepoling bar utilizes two temporary supporting forepoling bar suspension devices of the full anchor-cable supporting roadway. The device is simple in manufacturing technology, flexible in operation and high in adaptability, it can be ensured that after coal cutting (blasting), the full anchor-cable supporting roadway can be effectively supported temporarily, by adopting the suspension device, an origina
