At the mine entrance, the stone was loaded onto the wagons of a wooden gravity railway that led 1.5 miles downhill to the Avon Navigation, where further cranes were used to load the stone onto barges for transport to Bath and beyond.

A key step in designing an underground dimension stone mine in the Orosei area was of course to obtain an accurate geo-mechanical characterisation of the rock mass. From these results it was decided to adopt the ´rooms and pillars´ method.

These catacombs are the result of stone mining, particularly coquina (a soft limestone of broken shells), and consist of a network of basements, bunkers, drainage tunnels and storm drains. The catacombs also contain natural caves and span over 1,500 miles.

Since groundwater naturally percolates through pores and porous zones, it enters the mine workings as soon as excavations are created, whether above or below ground. The mine water reaches the aquifers and aquitards through the …

Stone mining played a vital role in the rebirth of 18th century Bath and Combe Down is a part of this World Heritage Site. Ralph Allen (1693-1764) did the most to raise the profile of Bath stone and he is one of the men credited with the expansion of Bath.

The Kentucky Stone Company operated a large above-ground and below-ground limestone quarry in Mullins (Withers), Kentucky. Mullins, originally named Withers after a large local family, was established along the L&N's Kentucky Division mainline in June 1886.

On Oct. 2, 2006 I revisited the Heavener Runestone and the Heavener Mine site. I studied the Runestone and it's surroundings to try to determine whether the claim that it had slid off the mountain above and left a discernable groove might be true. I found no evidence of that.

Underground mining of dimension stone is carried out at several sites in Italy. It is currently performed using technologies that do not cause damage to the material, i.e. without the use of explosives. There are more stability problems than with opencast quarrying, because of the empty spaces (rooms or chambers) created, …
