Polymeric chemicals are used in the flocculation process in coal mining to treat waste water by making particles clump together and float to the top, making them easier to be removed. Chemicals are huge potential risks to workers health, with burns, poisoning and respiratory problems all risks related to exposure to chemicals.
Coal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed. Regrading begins as coal excavation continues.

Coal seam gas (CSG) mining is a risky, invasive form of unconventional gas mining. Coal seam gas extraction usually involves tens of thousands of gas wells, with roads, pipelines, compressor stations, wastewater dams, and other infrastructure. A CSG project can spread across hundreds of thousands of hectares of land.
AUSTRALIAN mining companies are using highly toxic chemicals to extract coal seam gas during the controversial process known as ''''fracking'''', documents obtained by the Herald show.
