Honister Slate Mine
The Honister Slate Mine in Cumbria is the last working slate mine in England. Quarrying for Westmorland green slate has been taking place in the area since 1728. Apart from the mining it is also a popular tourist attraction in the Lake District National Park. History Opencast quarrying had been carried out at Honister since the late 17th century. But as capacity increased, the site's underground workings were extensively expanded. 19th century By 1870 Honister's underground workings stretched under Honister Crag with intermediate workings on the opposite side of the valley at Yew Crags. Smaller-scale underground workings on Dubbs Moor, together with a small opencast quarry. Packhorse teams had been used to remove the finished slate on sleds from mines. This involved bringing the loads down steep paths that traversed the cliffs to the top of Honister Pass (The Hause). Dubbs mine was known for its 'smaller metal' (metal being the terminology for slate), in that smaller pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zip Wire
A zip-line, zip line, zip-wire, flying fox, or death slide is a pulley suspended on a cable, usually made of stainless steel, mounted on a slope. It is designed to enable cargo or a person propelled by gravity to travel from the top to the bottom of the inclined cable by holding on to, or being attached to, the freely moving pulley. It has been described as essentially a Tyrolean traverse that engages gravity to assist its speed of movement. Its use is not confined to adventure sport, recreation, or tourism, although modern-day usage tends to favor those meanings. History Ropeways or aerial cables have been used as a method of transport in some mountainous countries for more than 2,000 years, possibly starting in China, India and Japan as early as 250 BC, remaining in use in some remote areas in China such as Nujiang (Salween) valley in Yunnan as late as 2015 before being replaced by bridges. Not all of these structures were assisted by gravity, so not all fitted the definit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fleetwith Pike
Fleetwith Pike is a fell in the English Lake District in the county of Cumbria which reaches a height of 648 metres (2,126 feet). The fell is a well-known feature of the area as it casts an imposing presence over Buttermere and the Honister Pass on the B5289 motor road between Borrowdale and Buttermere. Topography Fleetwith Pike is the north-western shoulder of Grey Knotts. It is bounded by Honister Pass to the north and Warnscale Bottom to the south-west, their two streams uniting beneath the fell in Buttermere. The north west ridge rising almost from the lakeshore at Gatesgarth is named Fleetwith Edge, and is a striking feature from any direction. The top of the fell is situated directly at the top of the edge, while a lower summit stands to the east atop Honister Crag. Fleetwith Pike is lined on all sides by impressive crags, other than for the broad plateau leading across the Drum House to Grey Knotts. Slate extraction The side of the fell which overlooks Hon ...

Safety Harness
A safety harness is a form of protective equipment Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, ele ... designed to safeguard the user from injury or death from falling. The core item of a fall arrest system, the harness is usually fabricated from rope, Wire rope, braided wire cable, or webbing, synthetic webbing. It is attached securely to a stationary object directly by a carabiner, locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a shock absorber, shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is reached. An unrelated use with a materially different arresting mechanism is bungee jumping. Though they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Via Ferrata
A via ferrata (Italian for "iron path", plural ''vie ferrate'' or in English ''via ferratas'') is a protected climbing route found in the Alps and certain other locations. The term "via ferrata" is used in most countries and languages except notably in German-speaking regions, which use ''Klettersteig''—"climbing path" (plural ''Klettersteige''). Infrastructure A via ferrata is a climbing route that employs steel cables, rungs or ladders, fixed to the rock to which the climbers affix a harness with two leashes, which allows the climbers to secure themselves to the metal fixture and limit any fall. The cable and other fixtures, such as iron rungs (stemples), pegs, carved steps, and ladders and bridges, provide both footings and handholds, as well. This allows climbing on otherwise dangerous routes without the risks of unprotected scrambling and climbing or the need for technical climbing equipment. They expand the opportunities for accessing difficult peaks as an alternative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narrow Gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

Bethesda, Wales
Bethesda (; ) is a town and community on the River Ogwen and the A5 road on the edge of Snowdonia, in Gwynedd, north-west Wales. It is the fifth-largest community in Gwynedd. History The settlement's ancient name was Cilfoden, formerly known as Glanogwen. In 1823, the Bethesda Chapel was built and the town subsequently grew around and later named after it. The chapel was rebuilt in 1840. The town grew around the slate quarrying industries; the largest of the local quarries is the Penrhyn Quarry. At its peak, the town exported purple slate all over the world. Penrhyn Quarry suffered a three-year strike led by the North Wales Quarrymen's Union between 1900 and 1903 – the longest industrial dispute in British history. This led to the creation of the nearby village of Tregarth, built by the quarry owners, which housed the families of those workers who had not struck. It also led to the formation of three co-operative quarries, the largest of which Pantdreiniog dominated the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penrhyn Quarry
The Penrhyn quarry is a slate quarry located near Bethesda, North Wales. At the end of the nineteenth century it was the world's largest slate quarry; the main pit is nearly long and deep, and it was worked by nearly 3,000 quarrymen. It has since been superseded in size by slate quarries in China, Spain and the USA. Penrhyn is still Britain's largest slate quarry but its workforce is now nearer 200. History The first reference to slate extraction at Penrhyn is from 1570, when the quarry is mentioned in a Welsh poem. The quarry was developed in the 1770s by Richard Pennant, later Baron Penrhyn. Much of his early working was for local use only as no large scale transport infrastructure was developed until Pennant's involvement. From then on, slates from the quarry were transported to the sea at Port Penrhyn on the narrow gauge Penrhyn Quarry Railway built in 1798, one of the earliest railway lines. In the 19th century the Penrhyn Quarry, along with the Dinorwic quarry, dom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred McAlpine
Alfred McAlpine plc was a British construction firm headquartered in Hooton, Cheshire. It was a major road builder, and constructed over 10% of Britain's motorways, including the M6 Toll (as part of the CAMBBA consortium). It was listed on the London Stock Exchange until it was acquired by Carillion in 2008. History Alfred McAlpine was one of the sons of 'Concrete' Bob McAlpine and he ran the operations of Sir Robert McAlpine in the north west of England. In 1935, following the death of Sir Robert and his eldest son, Alfred ran the north west independently, although the legal separation was not completed until 1940, when Sir Alfred McAlpine & Son was formed. Under a non-compete agreement with its former parent company, Sir Alfred McAlpine confined itself to civil engineering and to the north west of England. After the death of its founder, his son Jimmie McAlpine became chairman. The company was floated on the London Stock Exchange in 1958 under the name Marchwiel Holdings, ch ...
