About the Build
Pyroclast Mine is one of the best skills in the game for killing bosses with very little gear at league start. It deals tons of damage and scales with spell damage stats as well as mine-specific stats like Mine Throwing Speed. 
Charged Mines Support makes power charge and frenzy charge stacking into excellent damage bonuses, as well.
Scion's position in the middle of the passive tree is a good starting point for mine builds, and Scavenger is an all-around powerful ascendancy. It has good tankiness against Physical damage due to being able to stack 
Cloak of Flame with the 30% Phys-to-Fire conversion defensive Ascendancy bonus of the same name.
The Ascendancy bonus that grants 
Void Battery's extra Power Charge and Spell Damage per power charge is also very strong due to the charge-stacking nature of the build.
Leveling
Use 
Stormblast Mine from level 2 and make your way up to 
Destructive Apparatus so you can grab the "Detonate Mines is Triggered while you are moving" Mine Mastery bonus toward the end of Act 1.
Once you kill Gravicius in Act 3, you can swap over to Pyroclast Mine.
Upon completing Siosa's quest in The Library, you can buy 
Detonate Mines. Connect Detonate Mines and 
Automation, and remove the "Detonate Mines is Triggered while you are moving" Mine Mastery.
Use Charged Mines Support and 
Minefield Support as soon as you unlock them.
Gearing and playing this build during the campaign is extremely easy. Just get enough life and resistances to survive, and blast enemies with Pyroclast Mine!
