Grime's Graves Flint Mines

Knappers' rot. Silicosis in East Anglian flint-knappers.

ALONG THE line of the prehistoric trackway Icknield Way, a ridge of chalk, five miles wide, extends through west Norfolk to north-west Suffolk.' Beneath it lies-a seam of floorstone flint that Neolithic men exploited when they dug a series of large and elaborate mines to extract the flint at a site in south-west Norfolk now known as Grime's Graves. Over the succeeding four thousand years when t...

A Brief History of Mine Ventilation

Observations of the movements of air in underground passages have a long and fascinating history. Between 4000 and 1200 BC, European miners dug tunnels into chalk deposits searching for flint. Archaeological investigations at Grimes Graves in the south of England have shown that these early flint miners built brushwood fires at the working faces—presumably to weaken the rock. However, those Neo...

EHPnet: Mines, All Mines

The presence or absence of an oestrogen receptor-related antigen in breast tumours has been examined histochemically using a monoclonal antibody ('D59 Coffer & King, 1981). In frozen sections, fixed either by the method of Tamura et al. (1980) or in methanol, staining was apparent in 14/24 (58%) and 22/26 (85%) of the breast cancers respectively. In paraffin sections fixed in ethanol, staining ...

NTL vs FLINT

All tests were carried out on a very lightly loaded machine with a 64-bit Intel “Haswell” CPU (Intel Xeon CPU E5-2698 v3 at 2.30GHz) with plenty of memory (over 250GB). The operating system was Cent OS. The compiler was gcc v4.8.5. We compared NTL v9.9.1 with FLINT v2.5.2. These were both built using GMP v6.1.0. All of these were the most recent releases of these packages at the time we carried...
