Open-pit coal mining in the United Kingdom is in decline. Output has fallen every year since 2010. In 2010, the United Kingdom was forecast to produce about ten million tonnes (9,800,000 long tons; 11,000,000 short tons) of coal a year from open-pit mines.Most came from Scotland, with the largest operator there being the Scottish Coal subsidiary of Scottish Resources Group.

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Mar 13, 2018· Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly.
