Flint mining is the process of extracting flint from underground. Flint mines can be as simple as a pit on the surface or an area of quarrying, or it may refer to a series of shafts and tunnels used to extract flint. Flint has been mined since the Palaeolithic, but was most common during the Neolithic.
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, [1] [2] categorized as the variety of chert that occurs in chalk or marly limestone. Historically, flint was widely used to make stone tools and start fires. Flint occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.
The site is dotted with millions of scraps of worked flint and numerous mining pits, that Neolithic settlers have gradually turned into vertical mine shafts to depths of over 10 m (33 ft). Underneath is an elaborate man-made network of caverns accessible via the many shafts.
The general idea behind the ball mill is an ancient one, but it was not until the Industrial Revolution and the invention of steam power that an effective ball milling machine could be built. It is reported to have been used for grinding flint for pottery in 1870. [1]

Bagger 288 (Excavator 288), previously known as the MAN TAKRAF RB288 [4] built by the German company Krupp for the energy and mining firm Rheinbraun, is a bucket-wheel excavator or mobile strip mining machine. When its construction was completed in 1978, Bagger 288 superseded Big Muskie as the heaviest land vehicle in the world, at 13,500 tons. [5]

Grime's Graves is a large Neolithic flint mining complex in Norfolk, England.It lies 8 km (5.0 mi) north east from Brandon, Suffolk in the East of England.It was worked between c. 2600 and c. 2300 BCE, although production may have continued through the Bronze and Iron Ages and later, owing to the low cost of flint compared with metals.
