In Engpsh, a "mining machine" or "excavator" is commonly referred to as a "digger." You could also refer to it as a "bulldozer," "backhoe," or "loader," depending on the specific type of machine and its intended use.

For example, you might say: "I saw a giant digger at the construction site today. It was moving tons of dirt and rocks with ease."

Alternatively, you could say: "The bulldozer was clearing the land, making way for the new development. It was impressive to watch it work."

It's worth noting that the specific terminology can vary depending on the context and region, so it's always a good idea to be specific when describing a machine or piece of equipment.
