In Minecraft, mining is a key activity where players dig underground to collect valuable resources. These resources include ores like coal, iron, gold, and diamond, which are essential for crafting tools, armor, and other items. Players use various tools, primarily pickaxes, to break blocks and gather materials. Mining can be done in different ways, such as strip mining, cave mining, or branch mining. Each method has its advantages and can lead to discovering rare resources. Players must also be cautious of hazards like lava and monsters that can appear while exploring underground.
