There are two main methods of underground mining: roomandpillar and longwall mining. Roomandpillar mining. In roomandpillar mining, coal deposits are mined by cutting a network of ''rooms'' into the coal seam and leaving behind ''pillars'' of coal to support the roof of the mine.
This paper reviews underground mining methods for total thickness of a thick coal seam in single lift (TTTCSSL). Review shows the required engineering for extraction of thick seams needs to be fitted with thickness of the seam, behavior of rockmass and surrounding stress conditions for efficient mining.
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.
