The death of a well-respected Queensland farmer has sparked renewed calls for changes to coal seam gas mining laws and a royal commission into the industry.

George Bender, one of the first farmers to say no to CSG, took his own life on Wednesday night after a 10-year fight to keep Origin Energy off his 2000-acre farm in Hopeland, just south of Chinchilla.

The death prompted Queensland Senator Glenn Lazarus to call for a freeze on the controversial mining practice.

He told Macquarie Radio the industry was "bullying", "berating" and "threatening" farmers in the area daily.
