Abstract of the Disclosure A working platform for a drilling apparatus for stoping shafts, said drilling apparatus comprising a base (3) displaceable in the direction of the shaft (1) and a supporting arm (5) pivotably supported on said base. On the supporting arm is mounted a drilling device (8). The working platform (10) is fastened to the supporting arm by means of an articulated means (11) which permits a pivoting of the working platform with respect to the supporting arm around two pivot axes (B, C) perpendicular to each other so that the working platform pivots synchronously along with the drilling device as the supporting arm is rotated for drilling holes in the shaft in the shape of a fan and is adjustable into a horizontal position irrespective of the rotary position of the supporting arm.
