Today's march is backed by the miners' union, Grey District Mayor Tony Kokshoorn, West Coast-Tasman MP Damien O'Connor and Pike River Mine families spokesman Bernie Monk.
Engineering, Printing and Manufacturing Union West Coast organiser Garth Elliot said the rally would show the strong community support for keeping Spring Creek open.
"Our community has been absolutely battered in recent years, first with the Pike River tragedy and now this. We're marching together to say to Solid Energy and to the Government that they can't just abandon Greymouth.
"Coal prices go up and down, but mining communities have to go on. We're asking Solid Energy and the Government to take a real look at the damage that the closure of Spring Creek would do to the town and its people.''
Mr Kokshoorn said the march was not a "witch hunt'', but the community showing it was worried.
