Mary and Dakota

Surface Mining

Strip- Rectangular cuts in the ground where minerals can be extracted

Open Pit- tunneling into the earth to extract rocks and minerals

Mountain Top Removal- coal seams are extracted by removing the summit of a mountain

Subsurface

Slope- The slope makes it easier for the oil and coal to 'slide' out

Drift- Horizontal Mining accessed by adits

Shaft- Near vertical shaft to get oil

Fracking
