There's lots to see hear so we had to get back to the truck - we were killinh time waiting for the blasting to finished up at the American Eagle mine which is in the back ground.
Participants in NASA's 7th annual Robotic Mining Competition tote their robotic excavators to the competition arena. The RMC is set up for college students to design and build a mining robot that can travel over a simulated Martian surface, excavate regolith and deposit as much of it as possible into a bin, all within 10 minutes. Team members may control their bots remotely from a trailer where their only line of sight is via a computer screen, or completely autonomously, with their programming skills put to the test as their robot handles the mission on its own. The competition, which takes place May 16 to 20 at the Kennedy Space Center Visitor Complex in Florida, focuses on technologies necessary to extract consumables such as oxygen and water to support human life and provide methane fuel to spacecraft.

As you drive down through the often dark gorge of the A6 from Buxton to Bakewell, towards King Sterndale, you pass this curious building up on your right amongst the trees. Built on a steep slope with a semi-ornate exterior I have always wondered what it is. I can only assume it is linked to the mining and quarrying activities all over this area but does anyone know anything more about it?
On 1 January 1947 the post-war Labour government delivered on its manifesto commitment to take the lion's share of the British coal-mining industry into public ownership. By section 1(1) of the Coal Industry Nationalisation Act 1946/c.59 the mining of coal in Great Britain became, āsave as in this Act providedā, the sole prerogative of the National Coal Board.
The former Richard Evans & Co Ltd collieries were at first incorporated into No. 3/St Helens Area of the NCB's North Western Division. Further administrative reorganisation of the NCB estate followed as the number of operational pits in the Area reduced over the subsequent decades. The Board presented this account of the state of affairs at Golborne in 1967:
āNo.1 Shaft is 14 ft in diameter and was sunk in 1880 to the Lower Florida Seam at a depth of 150 yards. When the coal was worked out it was filled in 1943.
No 2 Shaft is the main upcast ventilation shaft and is 14ft in diameter. it was sunk to the Florida at a depth of 150 yds in 1880 and was deepened to 280yds in 1890 to the Wigan seams and again in 1902 to a point 80 yd below the Arley seam a total depth of 600 yds. It is used for manriding and materials
No 3 shaft is the downcast ventilation and coal winding shaft. It is 18ft in diameter and was sunk to a depth of 600 yd in 1902. It is also used for winding materials and men...
The present colliery is divided into two parts by an east/west fault which has a downthrow 180 feet north. The northern area has been extensively worked in the past and at present no coal is being worked in this area. A conservative estimate of the reserves available at the colliery is 29,000,000 tons giving a life of over seventy years at the planned output of 1,650 tons per day.
In 1949 two level tunnels were driven to investigate the south area. these tunnels reached the Wigan Four feet seam and in doing so proved the Peacock and the Trencherbone seams. Development in the Wigan Four Foot seam, for some 1200 yd across the take, proved the area to be promising and the Trencherbone and lower Florida seams are now being worked. The tunnels have now been extended to the Crombuke seam.
To enable the colliery to build up its output and to exploit the south area to the best advantage, a reorganisation scheme has been carried out. The scheme included for the introduction of a diesel haulage locomotive, the reorganisation of the pit bottom to reduce manpower, the electrification of the surface winders, the erection of pit head baths and the provision of adequate ventilation and compressed air.
SHAFTS AND WINDING
a) No.2 Shaft.
The original steam driven winding engine was manufactured by John Woods and Sons in 1896 and had two cylinders 30ā³ in diameter, with a 60ā³ stroke. This has now been replaced by a new winding engine manufactured by Metro-Vicks/John Wood and installed in July 1956. It is single cylindrical drum type, having a diameter of 15 ft and a drum width of 8 ft. The drum is driven through a double reduction gearing, ratio 34 to 1, from a 2.2k.v. slip ring induction motor of 200 hp at 575 rpm.
b) No 3 Shaft.
The original winder was built in 1907 by Fraser Chalmers and consisted of a pair of compound engines with cylinders 28ā³ and 46ā³ in diameter, with a 60ā³ stroke. The engines were very lightly built and had been in operation for fifty years and owing to the threatened closure of the colliery on two occasions, had not been adequately maintained. This winder was replaced in July 1956 by a new electric winder manufactured by Metro Vicks/Vickers Armstrong and is a of a double compartment single cylindrical drum type, having a diameter of 16 feet and an overall drum width of 8 ft. it is driven through a single reduction gearing from an 11kv slip ring induction motor of 1400 hp at 356 rpm.
COAL HANDLING ARRANGEMENTS
a) Surface.
On the surface, pneumatic decking rams are used to load and unload the cages at No 3 shaft top and the tubs are controlled by associated retarders and stops
b) Underground.
Prior to 1951, simultaneous decking was in operation at No 3 shaft. the pit bottom had now been completely reorganised with fully automatic control of full and empty tubs. The full tubs are left by the locomotive about 100 yds from the shaft and gravitate to the cages. They are controlled by retarders until they reach the uncoupling station, from which point they gravitate to the decking plant adjacent to the shaft. From here they are under the control of the onsetter, who operates the automatic rams, tilting platforms and other cage gear. The empties gravitate from the shaft on a series of creepers which moves the tubs forward for assembly in readiness for the locomotives which operate in the main transport system. the locomotive haulage system id handled by 70 hp diesel locomotives.
COAL PREPARATION
The run-of-mine coal is tippled on either of two classifying screens and classified into large +6ā³,
Cobbles 6ā³ x 3ā³ and -3ā³.
The +6ā³ passes along a picking belt and is cleaned by hand.
The 6ā³ x 3ā³ size is cleaned mechanically by a Greaves wash-box.
The -3ā³ is conveyed to a surge bunker and is fed out at a constant rate and delivered to a high speed screen.
This high speed screen gives two products, 3ā³ x Ć ā which is sent away for washing and Ć ā x 0ā³ which is sold untreated.
VENTILATION
Ventilation is provided by a Walker Indestructible Fan installed in 1908. the fan is 20 ft in diameter and 7ā² 6ā³ wide and was designed for a duty of 350,000 cfm at 4ā³ water gauge running at 129 rpm.
The original steam drive was by half compound engine developing 176 bhp but this was replaced in 1955 by an electric drive housing a 300 hp AC synchronous motor running at 300 rpm. In order to meet future requirements, a new exhausting single inlet radial flow fan of the backward aero-foil bladed type has been erected on the surface in anew fan house. The fan is capable of passing 360,00 cfm at 10.5ā³ water gauge; it is driven by a 800 hp synchronous induction motor through a three speed gearbox to give the flexibility of performance.
POWER SUPPLY
a) Steam.
The original steam raising plant consisted of a battery of six Lancashire Boilers, five of which were normally in steam and one kept as spare. they were installed in 1906 and were in a very poor condition. With the electrification of the surface plane, it had been necessary to keep only two boilers, one as stand bye to provide low-pressure steam for space heating and the surface buildings.
b) Compressed air.
There are two main units at the colliery, both by Bellis & Morcom, two-stage double crank vertical reciprocating air compressors each with a capacity of 2100 cfm. Both are electrically driven by 400 hp 2200 v motors. There is an 8ā³ diameter compressed air range in the No 2 shaft and the districts are supplied by 6ā³, 4ā³ and 3ā³ ranges. This capacity was not adequate for the future needs of the colliery and the supply had been augmented by a 1,100 hp electrically driven set with a capacity of 5250 cfm. This addition compressor is housed in an extension to the existing compressor house.
c) Electricity.
Electricity is obtained from the North Western Electricity board at 11000 volts transformed down to 2200 volts by means of 3x 1500 KVA transformers. The electricity supply underground is at 2200 volts and is supplied by shaft cables down No 3 shaft.
OTHER SURFACE BUILDINGS
a) Baths: A new pithead baths has been erected having accommodation for 1092 workmen and 12 officials. The building incorporates a canteen, medical centre and offices.
b) Lamproom: The lamproom has a capacity for 1100 lamps.
c) Stores: These are housed in a new stores building and materials stockyard.
MINING CONDITIONS
The measures in the Golborne Colliery take an average gradient of 1 in 4 in the south-easterly direction. The area also has a considerable amount of minor faulting, especially in the northern area. In the southern area, a high gas yield had been encountered and methane drainage is practised to provide safer working conditions.
OUTPUT
After reorganisation and up to 1960 an output of 1500 tons per day on two shifts was obtained from the Crombuke seam in the Northern area and the Trencherbone in the Southern area. Consequent to the exhaustion of the Crombuke seam in the north area, the output has been obtained in the South area of the Lower Florida and Trencherbone seams. In June 1961 three shift winding was introduced resulting in an increase in the average output up to 2250 tons per day. Coal is produced from four faces working double shaft on a shift rotation basis, giving colliery output on three shifts.
Power loading using the Anderton Shearer Loaders in conjunction with flexible armoured conveyors is employed on all faces and on the Trencherbone rise face Gullick āSeamerā 5-leg self-advancing powered supports are also in operationā.

The mine was a challenge to my preconceptions. In Kailo they mine wolframite and casserite. Before the war the mines were operated by a state run company, the defunct infrastructure can be glimpsed under bushes and vines. The company still has a smart office in the centre of the village, but instead of mining they take a percentage of the proceeds of the artisan miners and the traders. Most of the workers are from the area, although I met some from the province of Kasai. Children were working with their parents, helping with panning for the ore, carrying and selling goods to the workers. The mine is made up of widely dispersed open pits. Most pits were 4 to 10 metres deep with the occasional 25 metre pit. Next to the pits were the temporary huts of the workers. There did not appear to be the squalor or disease that we find in gold mines. Although there were Āmaison de toleranceĀ as they are politely called here with the associated risks of sexual diseases, AIDS and child prostitution.
As we left the mine we crossed two four wheel drive cars carrying men from a British company interested in investing in the mine.
I love the colors and how the side that faces the prevailing winds is totally aged and gray, but the other side still has some color in the wood.

I don't have any info on this place but all I know I've passed it for yrs and finally got tired of that so I stopped one day - but did find out that it's on Alvarado Rd which I thought was still Stanley Rd in this area - up from Stanley Rd - So my question is was there a mining town called Alvarado and is this a combination of 2 names - Al n Colorado????
Cripple Creek, Co. It was a great day walking around inspecting with what time we had for we had a couple other places to see while we was there.

Wyoming is characterized by a boom-and-bust energy-based economy. The state's leaders know better but can't help themselves.
That makes it all the more interesting to see the State of Wyoming post a sign telling the story of the biggest bust of all - Jeffrey City's uranium mining.

A rainbow was created by a full moon rising directly behind me as I took this shot. Sometimes referred to as a "moonbow," this is a rare occurrence given the number of variables that have to be just right for one to form. This moonbow rose over the historic Arizona mining town of Jerome.
