Bodie History: Drilling Blasting in the Bodie Mines
Beginning in the early 1860s, the industrialization of underground mining reached the western frontier and vastly improved the odds of profiting from quartz mining. Steam power was essential, but two other important inventions eased the miner's formidable task of drilling and blasting rock. Dynamite.
