The largest coal mining company, POLSKA GRUPA GÓRNICZA (PGG – Polish Mining Group) was established in May 2016 when the mines of its predecessor, KOMPANIA WĘGLOWA (KW), were transferred to this newly formed group. Then, on 1 April 2017, the mines previously owned by KATOWICKI HOLDING WĘGLOWY (KHW) were integrated into PGG. Other leading coal mining .
Surface mining is used for an estimated 40% of coal production. Used machinery equipment can be used to extract coal. Extracting coal is less expensive if it''s found near the surface. Once coal is extracted, the topsoil is then replaced and native trees and vegetation is planted to restore the original condition. There are three different types ...

For extracting coal which lies close the surface, huge dragline shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines. Surface mining may involve removing sections of hills or top layers of a flat surface area.
The drilling machine is commonly called a drill press and is responsible for drilling various sizes of holes in any surface area and to precise depths. Aside from the fact the drilling machine is used primarily in drilling holes, there are a few other functions that the drilling machine is capable of performing. These functions include tapping, spotfacing, reaming, countersinking, and ...
Surface coal mining generally involves the following sequence of unit operations: (1) clearing the land of trees and vegetation, (2) removing and storing the top layers of the unconsolidated soil (topsoil), (3) drilling the hard strata over the coal seam, (4) fragmenting or. land reclamation: Reclamation of mine spoils. This process is called surface mining and was widely used as a method ...
Surface mining equipment has been on the rise, increasing productivity but EPA regulations and climate debates have resulted in many combating through environmental activism. A series of mine tragedies in recent years have also contributed to unwanted attention and increased regulation. The below infographics outlines interest facts and trends with coal production.
