(CNN) Miners in eastern Kentucky are blocking a train loaded with coal from moving, saying the company they work for hasn't paid them since mid-December, CNN affiliate WYMT reported.

The group has been camping on the tracks outside the Quest Energy mine in Kimper, Kentucky since Monday. They said about 50 people have not been paid for their work since December 16 and will not go back into the mine until their paychecks are in their bank accounts, WYMT reported.

The mine owners, American Resources Corporation said Thursday that all employees "have been paid what they were owed."

"Unfortunately what they are demanding now is ransom and spreading lies at the expense of all of the rest of our amazing employees, which have reached out with great support for the company and their jobs," the company said in a statement. "It's unfortunate the lies that are being spread by them as it could cost all the rest of our 200+ employees future employment in an already challenged industry. We ... hope these few people understand their actions may put the rest of these hard working men and women out of work."

On Monday, the company said in a statement to CNN that it was behind eight days in paying some employees and others are just behind one day.
