 Context: The High Court of Karnataka has issued a ban on all mining and quarrying activities within a 20-km radius of the Krishnarajasagar (KRS) dam in Mandya district (due to concerns about the potential danger posed to the dam by these activities)

The ban applies to activities already permitted or in operation, and it will remain in force until a comprehensive study by experts is completed. The decision on lifting the ban will be made by the State Committee on Dam Safety, established under the Dam Safety Act, 2021.
