British Opencast Coal: a photographic history
Others are from the National Coal Board or British Coal Opencast archives. If there is a finer collection of images of walking draglines, scrapers and early mining excavators, I have yet to see it.

Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks
Surface Mining Methods and Equipment. Augering can be regarded as a supplementary method for open cast mining in cases when coal seams in the highwall would otherwise remain unmined (unless air conditioning if required, transportation to the surface, pumping, and Surface Mining Methods and Equipment J.

Mining Equipment Used For Opencast Coal. Coal Open Cast Mining Equipment Required mineral processing equipment and building materials equipment. And they are mainly used to crush coarse minerals like gold and copper ore, metals like steel and iron, glass, coal, asphalt, gravel, concrete, etc. With more than 2,500 case sites, the scientific management method, the refined Online inquiry
Guidance on the support of salvage faces in coal mines (Mines03) Supplementary guidance on the use of flexible bolts in reinforcement systems for coal mines (Mines04) Guidance on the design, installation and use of freestanding support systems (including powered supports) in coal mines; Coal mine roadway support system handbook
This guideline covers the open cast mining of ore bearing rock including coal. It excludes quarrying and open cast extraction of construction materials, stone and rock. (The processing of ore after extraction is covered in the Mineral Processing guideline as this is common to both open cast and underground mining operations.) Open cast mining
Openpit mining, or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Openpit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is
as iron, copper, coal and gold. There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal. This paper focuses on openpit surface mining, which involves removing ore from a large hole in the ground (sometimes referred to as a borrowpit). 1.
