What is a draft mine?

A draft mine is a type of mining operation that extracts minerals or resources from underground deposits, typically involving a vertical shaft or decline to access the ore. This method is often used for deeper mineral deposits that are not accessible through surface mining. Draft mines can utilize various techniques, including drilling and blasting, to break up the rock and transport the extracted materials to the surface. Safety measures and ventilation systems are crucial in these operations to protect workers from hazards associated with underground mining.
