In Dawn of Titans your gold mine generates gold for your kingdom which is needed to upgrade pretty much every building in the game.
The gold mine is one of a few buildings which you can build more than one of. You unlock additional gold mines as you upgrade your Castle.
Upgrading your gold mine increases the amount of gold generated per hour and the amount of gold it can store before your need to collect. You collect gold by tapping on your gold mines. You can also increase your gold production rate by using relics.
Gold is probably the most important resource in the Dawn of Titans, and your gold mines should therefore be one of the first buildings you upgrade. If you keep all your gold mines fully upgraded for your level you will progress much faster through the game.
Each level of your gold mine requires your Castle to be upgraded to a certain level first.
The table below has the build cost for each upgrade level, the build time, buildings required and the farm production and capacity.
