Hadronox Denied is a dungeon & raids achievement earned for defeating Hadronox in Azjol-Nerub on Heroic difficulty before he webs the top doors and prevents more creatures from spawning.
Strategy
To complete this achievement the party must reach Hadronox before he ascends the tunnel. This can either be achieved by jumping off the bridge or if a hunter/rogue/night elf/mage is in the group the hunter/rogue/night elf/mage can pull the Crushers that usually initiate the fight and 
[Feign Death]/
[Vanish]/
[Shadowmeld]/
[Invisibility]. The use of Feign Death/Vanish/Shadowmeld will cause the crushers to de-spawn and the party can simply walk down the tunnel to confront Hadronox as the fight re-sets.
It is important to avoid the mobs that constantly run down the tunnel to fight Hadronox, however they do not continuously spawn so it is possible to reach Hadronox without aggroing them. When you pull Hadronox it is imperative not to aggro the mobs in any way, thus any form of AOE should be avoided. The fight is very simple and in fact easier than the regular fight since the mobs help kill Hadronox.
If any member of the group does accidentally aggro the mobs then it it effectively means a wipe, not only will they attack you rather than Hadronox, when they die they will heal Hadronox. In such a case, the only option is to have a party member capable of high-threat instant AoE such as a mage or paladin immediately aggro the adds and kite them away from Hadronox while the rest of the group kills him.
Alternative Stategy
Wait until Hadronox ascends. Pull him before he wraps the doors. There will be lots and lots of small mobs; have your Tank tank them all. The DDs must burst down Hadronox before your Healer runs out of mana. Works almost always.
