First, miners drill a pattern of holes, which they then fill with explosives. Next, they detonate the explosives to break up the ground so it can be loaded into haul trucks. If the lode deposit is loed beneath the Earth's surface, underground mining is necessary. In this case, miners drill a shaft, or an adit, into the ground to access the lode.
