The New South Wales Minerals Council is supporting the call for more research into air quality along the Hunter Valley's rail corridors.
It comes after the Australian Rail Track Corporation (ARTC) released a report highlighting the need for more investigation into air quality monitoring.
According to the report it measured the level of suspended particulates and particle concentrations along rail corridors to determine whether loaded coal trains are a larger source of particle emissions than other trains.
The report found higher concentrations of particles coinciding with loaded and unload coal trains compared to passenger trains.
However it did find coal train levels were comparable to levels found during freight train passes.
NSWMC CEO Stephen Galiler said "the mining industry takes concerns about air quality seriously.
"Along with the power generation industry we have funded the establishment of the Upper Hunter Air Quality Monitoring Network to better understand air quality in the region, and we are working with regulators to reduce dust emissions from coal mines throughout the State.”
He added that the industry is committed to work with other industries, regulators, government, and the community to address concerns about air quality.
These tests follow wind tunnel test carried out by Xstrata Coal that indicated that the moisture content of the coal types test makes dust emissions from the surface of loaded coal wagons unlikely during transport from mine to port.
