In 2010, Shah Commission visited Goa, and soon they found several important facts that existed in Goa's mining industry. Some mining companies continued mining even if their leases were expired, some were mining outside the permissive mining area., some failed to maintain a required distance between overburden and irrigation canals.
All aspects above resulted in the fact that the production of iron ore exceeded the allowable output by more than 15%. Based on these negative impacts caused by mining industry, the state government shut down all 90 iron ore mines in Goa.
