Zusammenfassung:	The present invention provides a taphole cooling structure allowing prevention of wear and deformation of peripheral bricks of the taphole and maintaining stable operation of the furnace in high copper matte grade operations and high load operations. The taphole cooling structure is provided with a hollow jacket body to be inserted into an opening penetrated on a furnace wall, wherein a water passage is installed in the internal of the jacket body for circulating cooling water while a flange made of the same material as the furnace wall is provided on the periphery of said jacket body to be weldingly connected to the said furnace wall, wherein a refractory material is filled within a hollow of the said hollow jacket body and perforated with a taphole for draining solutions from the furnace body.
