Chatterley Whitfield
Chatterley Whitfield Colliery is a disused coal-mine on the outskirts of Chell in Stoke-on-Trent. It was the largest mine in North Staffordshire and was the first colliery in the UK to produce 1,000,000 tons of saleable coal in a year. In 1974 it was decided that Chatterley Whitfield coal could be more easily worked from Wolstanton Colliery and an underground roadway was driven to join the two pits. In 1976 coal drawing at Chatterley Whitfield came to an end. Two years later, a Trust was formed to establish the Chatterley Whitfield Mining Museum. The Museum opened to the public in 1979 and offered an underground tour of the disused tunnels to visitors, which included a trip down the main 700 ft. deep Winstanley access shaft. In 1989 the National Coal Board's national collection of mining artefacts was brought to Chatterley Whitfield for permanent exhibition, heightening hopes that the site would become Britain's primary mining museum. There were proposals to extend the attrac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pit Prop
A pit prop or mine prop (British and American usage, respectively) is a length of lumber used to prop up the roofs of tunnels in coal mines. Canada traditionally supplied pit props to the British market. As coal mining declined in importance and metal supports were used, the term became infrequently used. Though it was merely a log cut to a particular length, it was classified as a finished product and so got around the extra Canadian tariffs on the export of raw lumber. Because of the large quantities exported, it is probable many ended up in British pulp mills. Most pit props were made from the wood of spruce A spruce is a tree of the genus ''Picea'' ( ), a genus of about 40 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal ecosystem, boreal (taiga) regions of the Northern hemisphere.

Longwall Mining
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically thick). The section of rock that is being mined, known as the longwall panel, is typically long, but can be up to long and wide. The longwall method compares with shortwall, room-and-pillar, and several others. History The basic idea of longwall mining was developed in England in the late 17th century, although it may have been anticipated in the pre-industrial era by a similar technique utilized by the Hopi of Northeastern Arizona in the 14th century. Miners undercut the coal along the width of the coal face, removing coal as it fell, and used wooden props to control the fall of the roof behind the face. This was known as the Shropshire method of mining. While the technology has changed considerably, the basic idea remains the same, to remove essentially all of the coal from a broad coal face and allow the roof and overlying rock to collapse into the void be ...

Ratchet (device)
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ''ratchet'' is also used informally to refer to a ratcheting socket wrench. __TOC__ Theory of operation A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a '' pawl'' (or ''click'', in clocks and watches) that engages the teeth. The teeth are uniform but are usually asymmetrical, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e. forward) direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible 'click') into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the oppo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Federation Of Stoke-on-Trent
The federation of Stoke-on-Trent was the 1910 amalgamation of the six Staffordshire Potteries towns of Burslem, Tunstall, Staffordshire, Tunstall, Stoke-upon-Trent, Hanley, Staffordshire, Hanley, Fenton, Staffordshire, Fenton and Longton, Staffordshire, Longton into the single county borough of Stoke-on-Trent. The federation was one of the largest mergers of Local government in England, local authorities, involving the greatest number of previously separate urban authorities, to take place in England between the nineteenth century and the 1960s. The 1910 federation was the culmination of a process of urban growth and municipal change that started in the early 19th century. Little interaction between the separate settlements occurred until the 18th century when the pottery industry began to expand rapidly. By the early 19th century, initial steps had been made to ensure greater co-operation between the Potteries towns over the issue of law and order. The county plan of 1888 made th ...
