More than 14,000 public submissions have been made to the Department of State Development, Infrastructure and Planning regarding the environmental impact of a central Queensland coal mine.

Indian company Adani is proposing to build the Carmichael mine, about 160 kilometres north-west of Clermont in the state's Central Highlands.

The project will include open-cut and underground operations, as well rail infrastructure, which will be mostly within the boundaries of the Isaac Regional Council area.

A spokesman for the Department of State Development says a number of individuals and groups made comment about the proposal during the consultation period.

They included 16 government agencies, 15 organisations and 22 local landholders.

More than 14,000 people made submissions via third-party websites.

During the consultation period, Adani also provided public briefings in Moranbah and Clermont.
