It has a grid of 16-foot-high (4.9 m), 40-foot-wide (12 m) tunnels separated by 25-foot-square (7.6 m) limestone pillars created by the room and pillar method of hard rock mining. [1] The complex contains almost 10.5 miles (16.9 km) of illuminated, paved roads and several miles of railroad track.
The mine is the lowest point in Japan at 170 metres (560 ft) below sea level, [1] and digging still continues. The open pit has a north–south length of approximately 2 kilometers and an east–west width of 800 meters. The limestone excavated is transported by a 10 kilometer pipeline with belt conveyor to Port of Hachinohe.
The ancient Egyptians used nummulite shells as coins and the pyramids were constructed using limestone that contained nummulites. [ 3 ] [ 6 ] It is not surprising then that the name Nummulites is a diminutive form of the Latin nummulus 'little coin', a reference to their shape.

The Pinpet Mining Project is an open-pit iron ore mine in Mount Pinpet, Shan State, Myanmar. Plans for the project started in 2003, and construction of an iron ore factory has been underway since 2004. The Pinpet deposit consists of an estimated 10 million tons of hematite with 56.4% iron and reserves of limonite at 70 million tons with 42.6% iron.
This limestone, known as a "lumachella," formed under low-oxygen lagoonal conditions and contains abundant Lithiotis-type bivalves. Faces similar to those at Preserje near Borovnica indicate littoral zones with alternating subtidal and supratidal conditions, similar to the present-day Bahamas , with occasional high-energy oolitic limestone beds ...
The original source for lithographic limestone was the Solnhofen Limestone, named after the quarries of Solnhofen where it was first found. This is a late Jurassic deposit, part of a deposit of plattenkalk (a very fine-grained limestone that splits into thin plates, usually micrite) that extends through the Swabian Alb and Franconian Alb in Southern Germany.
