The Mine Belt is a band of Earths between the Ice Belt and the Corn Belt comprised of arid worlds with not enough trees to build a colony or a town.
Since the Ice Belt ends at Earth West 36,000, it can be deduced that the Mine Belt starts around Earth West 36,001. The Corn Belt starts at Earth West 100,000, so the Mine belt ends around Earth West 99,999.
In The Long War, it is revealed that the Mine Belt is full of minerals scarce on Datum Earth like Gallium, Germanium and Cobalt.
