Goron Mines

The Goron Mines are the second dungeon of The Legend of Zelda: Twilight Princess, located near the top of Death Mountain. The main item is the Hero's Bow, the miniboss is Dangoro, and the boss is Fyrus. Interestingly, Goron Mines is the only dungeon in the entire Legend of Zelda series in which neither the boss nor the mini-boss are actually killed.

Story
The patriarch of the Goron tribe and the four elders had ventured into their mines to investigate the recent appearance of many monsters. On their venture, the leader of the tribe, Darbus, was possessed by the evil power of the Fused Shadow and transformed into a raging beast, Fyrus. The Gorons, unaware of what to do, chained him up and locked him away deep inside the mines whilst they tried to return him to his true form.

After Link defeats one of the elders in a sumo wrestling match, he is granted access to explore the closed-off mines in order to rescue Darbus. Inside, he encounters Dangoro and defeats him. Dangoro then allows Link to enter the place where the Hero's Bow is kept. Link uses this item to enter the room where Fyrus is chained away. He defeats Fyrus and breaks the magical spell on the Goron Patriarch. He also recovers the second Fused Shadow.

Dungeon
The dungeon contains many settings, including lava-filled caverns, rocky pools, magnetic crystals, and storage rooms. There are also three shrines in the temple; Link must visit all of them in his journey, in order to meet all of the Goron Elders and thus reassemble the dungeon's Boss Key.

The dungeon item is the Hero's Bow, used by an ancient Goron hero (largely thought to be the Hero of Time) who saved the tribe in the past. After meeting with the elders, Link was permitted to wield this artifact, but only after he had defeated the dungeon's mini-boss, a huge Goron guard wearing thick armor, named Dangoro.

Theories
Due to the similarities between the two, it is possible that the Goron Mines and the Fire Temple from The Legend of Zelda: Ocarina of Time are one in the same.

Due to the latter being considered a mine by the Gorons, it is possible that the Goron Mines could be the Dodongo's Cavern from Ocarina of Time capitalized by Gorons.
