Question

which is a type of mining where overburden is stripped and coal is removed? hall mining strip mining leach mining placer mining

Strip mining is a surface mining method where layers of overburden (soil/rock covering the resource) are stripped away to access and remove underlying coal or other minerals, matching the description in the question. The other options do not fit: hall mining is not a standard mining term, leach mining uses chemical solutions to extract minerals, and placer mining targets sediment-borne minerals.
