Openpit mines are typically worked until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic [citation needed] After openpit mines are closed, they are sometimes converted to landfills for disposal of solid wasteSome form of water control is usually required to keep the mine pit from becoming a lake
