Which is true about surface mining?
It is the expensive and dangerous than underground mining.
.In surface mining the soil and rock that covered the ores are removed through blasting.
Surface mining can be done through creating a tunnel beneath the Earth's surface
It used to extract ore minerals beneath the earth's surface or underground.
