The original purpose of the device was to mine Naquadria. Neighboring nations Tirania and the Andari Federation were unaware of its construction until their planet was rocked by massive earthquakes, denoting a disturbance of unstable Naquadria deep underground.

They returned to the surface with no loss of life. (SG1: "Fallout")
