The extraction of coal and coal seam gas (CSG) will generate produced water that if not adequately treated will pollute surface and groundwater systems In Australia the discharge of produced water from coal mining and related activities is regulated by the state
Underground mine fires generally start in just that underground mines The coal gives them a seemingly endless supply of fuel they've had something to get them started and they get oxygen from the ventilation system that extends up to the surface Coal seam fires can get started in a variety of natural and man-made ways
Dec 09 2014In a recent article on The Conversation Queensland coal seam gas (CSG) researchers argued that the industry is progressing faster than the science leading to

Mining for coal depends on many variables The geology and environmental aspects play a vital role but depth and quality of the seam is what brings home the bacon Depending on where the seam (profitable bed of coal) is located extracting this black gold can require a smorgasbord of options Coal

"Coal (mining) is one of the most regulated industries there is in Queensland " he said One objective of the study would be to determine likely future customers for the mine's output He said tests indicated the area had high-quality coal seams up to 10m thick which could be strip-mined very efficiently with a very small footprint on the

The Ji 15 coal seam of the mine is highly gassy has low permeability and does not have a protective seam which is the requisite condition for conventional mining This study proposes a coal mining technique that integrates the processes of mining-dressing-gas draining-backfilling-mining (MDGBM) to address the previously mentioned challenges

determined by how the coal seam is situated If a coal outcrop appears at the surface of a hillside a "drift mine" can be driven horizontally into the seam Where the bed of coal is close to the surface yet too deep for surface mining a slope mine can be constructed with the mine shaft slanting downward from the surface to the coal seam
