Podzemní zásobník plynu Háje, Underground gas storage facility in Příbram, Czech Republic

Podzemní zásobník plynu Háje is an underground natural gas storage facility located near Příbram at a depth of about 950 meters within granodiorite rock formations. The storage complex consists of interconnected chambers capable of holding approximately 72 million cubic meters of gas, accessed through five production wells.

Construction of this storage facility began in 1992 when engineers recognized that Prague needed strategic buffer capacity for natural gas supplies. The project leveraged the geological properties of the site to create a secure, long-term storage solution.

The site sits by shaft No. 16 of a former uranium mine that operated from 1957 to 1991 and was called the deepest shaft in Central Europe. Visitors pass the junction of the Buk–Příbram and Konětopy roads near Jesenice and Milín, where the surface technology of the storage facility stands.

The site is not open to public visitors as it is an active industrial facility with strict operational security requirements. Information about the facility can be obtained through official channels with the operators.

Shaft No. 16, which the storage facility uses, operated from 1957 to 1991 and was described as the deepest shaft in Central Europe. The gas is held in a system of tunnels with profiles of 12 to 15 m² and a total length of 45 km, giving a volume of 620,000 m³.
