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.

Applicability of Proximity Detection to Mobile Underground Coal Equipment: A project to determine whether the proximity detection systems currently available to the underground coal mining industry provide protection to miners working near mobile haulage equipment such as shuttle cars and scoops. Proximity Detection; Jacob Carr: 1
Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof. Once room and pillar mines have been developed to a stopping ...
Types of coal mine. Shaft mine – Miners and equipment are transported down vertical shafts hundreds or thousands of metres deep to access fertile coal seams. Drift mine – The simplest method of underground mining, the coal seam is accessed by digging horizontally into the side of a hill.

One of the greatest challenges that exists in underground coal mining is the ability to accurately automate a longwall miner to follow a known target horizon. Longwall automation has now been achieved through the LASC Longwall Automation project conducted at CSIRO. However, the location of the coal seam horizon is still uncertain.
Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...

The coal can then be removed without the coal miners having to go deep underground. Underground mining is when the coal is farther underground, making it too expensive to remove soil. In this process, coal miners and all of the coal mining equipment are brought deep underground and coal is carried up out of the ground.

Choosing a mining method. The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors.
