A B S T R A C T A compact apparatus for drilling and plugging a taphole of a shaft furnace, the furnace including a tap channel through which molten metal may flow, the tap channel extending from the taphole in a direction generally radially with respect to the axis of the furnace. The apparatus for drilling and plugging the taphole includes a drilling device and a plugging device, each device mounted on the end of an arm, the arm pivotably mounted about an axis inclined from the vertical to allow movement of the devices in an inclined plane between a position of retraction and a position of operation. The arm of the drill device and the arm of the plugging device are positioned on one side of the tap channel and are installed on the tap floor. The axes of the drill and plugging devices are tilted with respect to each other and with respect to the vertical to allow the device nearest to the furnace to pass over the device farthest from the furnace when both devices are in the retracted position.
