Highwall mining is an important surface coal mining method, and it may account for approximately 4% of total U.S. coal production. Highwall stability is the major ground control related safety concern. Ground control plans for highwall mining should specify hole width, web pillar width, barrier pillar width and number of holes between barriers.

Open pit mining method works best when the deposit is close to the surface as it is way more economical to use this method instead of underground mining. Open pit mining operations are the largest operations world-wide. Since this method allows for the use of large equipment, it results in huge economies of scale, enabling immense cost savings.

Creating a steeper highwall in a pit expands the amount of mineable material in a surface mine or quarry at its outer boundaries. With the chain drive Terrain Leveler SEM attachment, you can cut up to a 90-degree highwall. With the single-sided direct drive Terrain Leveler SEM attachment, you can cut up to an 80-degree highwall.

The bord and pillar method of mining is suited to work flat coal seams of average thickness and at shallow depths. Coal seams of 1.8 to 3 m thickness are best suited for this method, though the method has been successfulin thinner seams also down to a thickness of 1.2 m and in thicker seams up to 4.8 m in thickness.

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 for such essential activities as human and ...
