· But briefly, strip mining is economically "necessary" to extract some mineral resources, such as coal, when the overburden is not too thick. In such cases, an underground mine would be costly and probably unsafe. Do a search in Socratic for this question "Is strip mining necessary?" and see if this answer helps with your question.
