The invention belongs to the technical field of vertical heading machines, and particularly relates to a vertical heading machine forepoling support which comprises a supporting support body. The supporting brackets are arranged in a pair; a plurality of groups of connecting rods are fixedly connected between the pair of supporting brackets; the periphery of the bottom of the vertical shaft can be supported through the blocking effect of the supporting bracket, the connecting rod and the telescopic fence, the pressure around a soil layer is kept when a water source is extracted, the collapse condition is reduced, meanwhile, the positioning block capable of moving is matched, the positioning block can enter the supporting bracket, and through the filtering effect of the filter screen, the water source is extracted. The bottom of the vertical shaft is provided with the supporting support, impurities existing at the bottom of the vertical shaft are extruded, the impurities are accumulated at the bottom of the su
