Ms Osborn said the group, which numbers around 70 people, had the backing of the Environmental Defender's Office, which had agreed to run the case against the Gujarat longwall on behalf of residents.
"We believe that the commencement of longwall mining by Gujarat NRE in the absence of an appropriate development consent is unlawful and irresponsible," Ms Osborn said.
"The application to commence longwall mining was not put on public exhibition, and there was no opportunity for public comment."
Ms Osborn also slammed the actions of the government departments responsible for allowing the development to proceed.
"The Department of Trade and Investment and the Department of Planning and Infrastructure have failed in their responsibility to ensure that mining approvals follow clear and transparent processes and consider the impact on residential neighbourhoods," she said.
