Dialogue
 * "Something troubles me about those plans. Whoever made them the first time, can probably make them again. I mean, they figured it out once already, right? If we want to stop them from making the blasted thing, we need to take away their means of production. I saw a group of engineers pulling a cart full of explosive barrels through here earlier heading towards the middle of the mines. Ye should be able to jump them and use those explosives to sabotage the levers."

Walkthrough
Upon entering the Iron Horse Mine, you will be faced with a fork in the road:
 * If you take the right fork, you will head to the Ettin cave (where you found Minaar earlier). Continue through the cave and you will come outside to the area where you found the boss carrying the plans in Minaar's Worry. Turn left on the narrow walkway before you get to that point and you should see the Dwarven Powder Keg Station.
 * If you take the left fork, the road will wind like the shape of an "S" and eventually you will arrive from the side of the levers. You will pass three sets before you get to the Dwarven Powder Keg Station.

The lever sets can be found around some sort of cablecar towers. When placing the Powder Kegs make sure to put them down in the middle between the three levers to blow all three up with one blast. While the supply of kegs is unlimited this limits the amount of running back and forth that is necessary. Checking the quest log after each blast will tell you whether you have gotten all three.
