Question

where are mines located? underground above ground in urban areas

Explanation:

Mines are typically located underground. Mining operations involve extracting minerals, ores, or other valuable resources from beneath the Earth's surface. While some surface - related activities (like open - pit mining which still has a significant underground component in terms of the ore body) or very rare cases in non - urban areas might seem to be "above ground" in a limited sense, the core location of the mine (where the main extraction of the valuable material occurs) is underground. Urban areas are not typical locations for mines due to space, environmental, and safety concerns.
