The invention discloses a method for urgently blocking a river dam breach based on an array rocket drilling ground anchor. The method comprises the following specific steps that (1) the rocket anchor is launched, an anchor cable is connected with a shore fixed pile, and a 'rooting strongpoint' is formed at the dam breach; (2) steel mesh stone cage sets are slidably thrown through the rocket anchor cable, and a 'tower of strength' for dam breach blocking and repairing is rapidly formed; and (3) through an anchor dot array, steel mesh stone cages are slidably thrown and connected to form an 'expanding main body' for dam breach blocking and repairing. Precise arraying is conducted through laser guidance, meanwhile, anchor tools are triggered and expanded through sensing, the anchor tools are firstly fixedly arranged and then combined to increase the area, thus a preset anchor array is rapidly formed at the dam breach, and then the steel mesh stone cages are slidably thrown through a plurality of channels to cons
