Commonly used mining techniques to extract coal ICSC

2018-1-25  As mining of coal depends on the depth and quality of the coal seams, different techniques are used to dig the deposits. Surface mining and deep underground mining are the two main methods of mining coal. Depth, density, and thickness of the coal seam are the factors that are taken into account while selecting the mining method for coal extraction.

Continuous miners Introduction underground COAL

The term "continuous" as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading.

Longwall Mining — Center for Coalfield Justice

Longwall mining is a deep mining technique capable of fully extracting huge panels of coal, frequently up to 1,500 feet wide and two miles long. Coal shearing machines known as “continuous miners,” remove a long wall of coal in a single slice as hydraulic jacks hold up the roof above and in front of the machine.

2017-6-16  Room-and-pillar mining may leave as much as 60 percent of the coal in supporting pillars after initial mining. Later, some of these pillars are removed as equipment retreats from the mined area.
