Blast Mining (Locked until level 125 Mining) Instead of using a pickaxe to break blocks, Blast Mining utilizes TNT to destroy and mine blocks. It is activated by using a flint & steel (shift and right-click the air between yourself and the TNT). With Blast Mining, the range at which the TNT ignites is extended. Higher Mining levels will yield more ores. By default, TNT drops 30% of what is blown up, and is increased further with each level.
