Chanois Coal Mine
The Chanois coal mine is one of the main shafts of the Ronchamp coal mines, in the French Communes of France, commune of Ronchamp, within the Haute-Saône department, belonging to the Bourgogne-Franche-Comté region. It was the center of Ronchamp's coal mining operations from the late 19th century until the mines closed in 1958. It was therefore chosen as the site for the coal mine's ancillary facilities, including a coal preparation plant, a Coke plant (fuel plant), coking plant, and a Ronchamp thermal power station, power station. It succeeded the Saint-Joseph Coal Mine, Saint Joseph shaft in 1895 and ceased mining in 1951. At the beginning of the 21st century, many remnants of these facilities (ruins, a large concrete hopper, converted buildings, and two imposing spoil tips) remain. Excavation Before 1873, the Ronchamp coal mining company operated in the center of the Ronchamp and Champagney coalfields. But the Shaft sinking, shafts used for this task reached the end of thei ...

Ronchamp
Ronchamp () is a commune in the Haute-Saône department in the region of Bourgogne-Franche-Comté in eastern France. It is located between the Vosges and the Jura mountains. Mining Museum Mining began in Ronchamp in the mid-18th century and had developed into a full industry by the late 19th century, employing 1500 people. The museum looks back at the miners' work, the techniques and tools they used, and their social life. A collection of miners' lamps is also on display. Notre Dame du Haut The chapel of Notre Dame du Haut, designed by Le Corbusier, is located in Ronchamp. It is a shrine for the Catholic Church at Ronchamp and was built for a reformist Church looking to continue its relevancy. Warning against decadence, reformers within the Church looked to renew its spirit by embracing modern art and architecture as representative concepts. Marie-Alain Couturier, who would also sponsor Le Corbusier for the La Tourette commission, steered the unorthodox project to completion ...

Shaft Sinking
Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects. Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means. Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa. The modern shaft sinking industry is gradually shifting further towards greater mechanisation. Recent innovations in the form of full-face shaft boring (akin to a vertical tunnel boring machine) have sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sainte Marie Coal Mine
The Sainte Marie Coal Mine is one of the major Ronchamp coal mines, located in Bourlémont (Ronchamp, Haute-Saône), in eastern France. It was worked intermittently between 1866 and 1958, then finally closed. The concrete headframe was reinforced in 1924 by Charles Tournay. This Liège engineer and architect specialized in constructing concrete headframes. On 29 March 2001, the headframe was listed as a French national ''monument historique''. et Background In 1830, a survey was conducted atop Bourlémont Hill, near the eventual site of the Sainte Marie Coal Mine, but no trace of coal was discovered. By the 1860s, the Stéphanien coal basin had been found, and the Saint-Charles, Saint-Joseph, Sainte-Pauline, and Sainte-Barbe mines were opened. Also ongoing at that time was the unsuccessful digging of the Saint-Georges pit. Mining In 1863, it was decided that the Saint-Charles mine should be replaced by a new mineshaft to be dug to its west. The limits of the Ronchamp basin w ...

Electric Light
An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet cap. The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, such as fluorescent lamps, and LED lamps, which produce light by a flow of electrons across a band gap in a semiconductor. Before electric lighting became common in the early 20th century, people used candles, gas lights, oil lamps, and fires. Vasily Vladimirovich Petrov developed the first persistent electric arc in 1802, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pump
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: ''direct lift'', ''displacement'', and ''gravity'' pumps. Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis. When a casing contains only one revolving impeller, it is called a single-stage pump. Whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Germain Sommeiller
Germain Sommeiller (February 15, 1815 – July 11, 1871) was a civil engineering, civil engineer from Savoy. He directed the construction of the Fréjus Rail Tunnel between France and Italy, also known as the Mont Cenis Tunnel. This was the first of a series of major tunnels built in the late 19th century to connect northern and southern Europe through the Alps. Sommeiller pioneered the use of Jackhammer, pneumatic drilling and dynamite to achieve record-breaking excavation speeds. This 12.8-km tunnel was completed on December 26, 1870, 11 years ahead of schedule. It remained the longest tunnel in the world until the opening of the Gotthard Rail Tunnel in 1882. Life Germain Sommeiller was born in Saint-Jeoire (now part of Haute-Savoie, France) on February 15, 1815. He graduated in civil engineering at the University of Turin in 1841. He became a Royal Civil Engineer in the Public Transport Department of Savoy in 1845. From 1846 to 1850 he worked for the Société anonyme Joh ...

Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres. In Europe, 10 percent of all industrial electricity consumption is to produce compressed air—amountin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bourlémont
Bourlémont is a hill located in Ronchamp, Haute-Saône, eastern France with an elevation of above sea level. It is located in the Ballons des Vosges Nature Park, and is an area of cultural tourism, given that the chapel of Notre Dame du Haut is located on it. Toponymy In the 18th century, Bourlémont was described as "Notre-Dame-de-Bourg-les-monts", which indicates that there was a fortified town on the hill. At the beginning of the nineteenth century, the hill was called the "Bourg Mountain". Geography Bourlémont is located in Ronchamp, Haute-Saône, Franche-Comté, France. It can be accessed from Chapel Street on the southeastern side of the summit and the Way of the Cross footpath which was created in 1890. The GR 59 and Dukes hiking trails pass along the eastern side of the hill. The hill has an altitude of , meaning that it is higher than the centre of Ronchamp (), which is at the foot of the hill. Bourlémont is mainly composed of red sandstone, but there is also a pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dimension Stone
Dimension stone is natural stone or rock that has been selected and finished (e.g., trimmed, cut, drilled, ground, or other) to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements. Another important selection criterion is durability: the time measure of the ability of dimension stone to endure and to maintain its essential and distinctive characteristics of strength, resistance to decay, and appearance. Quarries that produce dimension stone or crushed stone (used as construction aggregate) are interconvertible. Since most quarries can produce either one, a crushed stone quarry can be converted to dimension stone production. However, first the stone shattered by heavy and indiscriminate blasting must be removed. Dimension stone is separated by more precise and delicate techniques, such as diamond wire saws, diamond belt saws, burners (jet-piercers), or light and selective blasting with Primacord, a weak explosive.

Winding Engine
A winding engine is a stationary engine used to control a cable, for example to power a mining hoist at a pit head. Electric hoist controllers have replaced proper winding engines in modern mining, but use electric motors that are also traditionally referred to as ''winding engines''. Early winding engines were hand, or more usually horse powered. The first powered winding engines were stationary steam engines. The demand for winding engines was one factor that drove James Watt to develop his rotative beam engine, with its ability continuously to turn a winding drum, rather than the early reciprocating beam engines that were only useful for working pumps. They differ from most other stationary steam engines in that, like a steam locomotive, they need to be able to stop frequently and also reverse. This requires more complex valve gear and other controls than are needed on engines used in mills or to drive pump A pump is a device that moves fluids (liquids or gases), or ...
