Jeronym Mine is situated in the west part of the Czech Republic in the area with rich mining history and it is a valuable example of preserved historical mining operations dating back to the 16 century, such as extraction using a picker and miner's hammer, fire setting, underhand stoping or overhand stoping, chamber mining, etc.
In the oldest stage of mining in the Jeronym mine, which began in the 16th century, the picker and miner's hammer were used for crumbling away the rock.
"It's fun" to chip sunstones out of the surrounding rock and soil with a small
miner's hammer, she said, "You can see what you're getting right away."
