The coal mining risk assessment includes an assessment of the Coal Authority Mining Report. The fundamental purposes of the coal mining risk assessment are to identify the risks of coal mining at the development site. The Coal Authority is a legal consultant for any planning application within a High-Risk Zone. Also, a visit to the offices of the Coal Authority to assess mining plans, a review of modern and historical published geological maps, and a review of technical reports/memoirs.

Coal Mining was quite extensive across Pott Shrigley in the eighteenth century, although the coalfield was small and badly divided by faults. Above Long Lane, which forms the boundary between Adlington and Pott Shrigley, there are a number of abandoned shafts which are easily spotted due to the plantations of trees over and around them. The planting of trees was a stipulation in the leases from the Downes family of Pott Shrigley. When a pit was finished and abandoned it was to be walled or fenced round and trees planted. The fences have long gone but the trees remain.
These pits were working the Bassy Mine (or seam) which averaged about 48ins thickness but was split up by a number of dirt bands. The shaft on the right is situated on the outcrop of the Ribbon MIne which was only about 10ins thick, whilst the Sweet Mine (18ins) outcrops just in front of the camera. Nab Farm can be seen in the centre, whilst to the left is another mound with trees which is probably the site of another shaft. Until the late 1970s these shafts were open, but they have since been capped.
Clothes put out to dry outside one of the huts in the transit camp setup by POSCO-India.
The transit camp of POSCO, India that has been set-up for the few villagers who are so-called "Pro-POSCO". However, interviews revealed that they have been kept here forcefully since they have nowhere to go and are given Rs.20/- (50 cents) a day per head by the government for all their expenses, including food and other ration. The condition of the camp is abyssmally low. There are about 52 families sharing around 20 toilets and bathrooms. The huts leak when it rains and conditions are extremely unhygienic specially for old people and children.

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.

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 to continuously 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 pumps.

Mining companies should continuously monitor and respond to the concerns of major groups and changes in the national or local situation.
In February 2000, an upstream tailings dams at the Baia Mare gold mine in Maramures County, Romania failed. The failure is thought to have been caused by a combination of poor design, unforeseen operating conditions and heavy rain and snow, which resulted in overtopping (BMTF 2000).
Two months later, this failure was followed by another upstream dam failure at the nearby Borsa lead and zinc mine, which also occurred as a result of overtopping. These two incidents released more than 200 000 cubic metres of contaminated water and 40 000 tonnes of tailings into tributaries of the Tisza River, a major tributary of the Danube (WWF 2000).
The Baia Mare spill was the most damaging of the two failures, releasing 50 to 100 tonnes of cyanide, as well as copper and other heavy metals, making it the worst environmental disaster in Europe since Chernobyl. Over a four-week period the combined spills travelled through Romania into Hungary, Serbia and Bulgaria, and finally entered the Black Sea. The spill traversed a number of ecologically sensitive and highly populated areas, with significant transboundary implications. Acute effects of the cyanide were observed along the river system to the point where the Tisza River meets the Danube. The Baia Mare failure created a 30- to 40-kilometre-long wave of contaminants that wiped out the flora and the fauna of the central Tisza River. Plankton were killed instantly by the plume; fish were killed in the plume or died soon after. In the Hungarian section of the river, the impact was especially severe – it is estimated that 1 240 tonnes of fish were killed (UNEP/OCHA 2000).
An international task force, chaired by the European Commission, was created to assess the damage and propose remedial actions (EU 2000). The task force insisted on the necessity of providing adequate emergency-storage facilities and recommended that new tailings storage facilities should not be allowed to store water or slurry containing cyanide in tailings ponds open to the elements (Lucas 2001).

The town of Butte, Montana (pronounced “byoot”) is known as the “Richest Hill on Earth” and "The Mining City". The Butte Mining District has produced gold, silver, copper, molybdenum, manganese, and other metals.
The area's bedrock consists of the Butte Quartz Monzonite (a.k.a. Butte Pluton), which is part of the Boulder Batholith. The Butte Quartz Monzonite ("BQM") formed 76.3 million years ago, during the mid-Campanian Stage in the Late Cretaceous. BQM rocks have been intruded and altered by hydrothermal veins containing valuable metallic minerals - principally sulfides. The copper mineralization has been dated to 62-66 million years ago, during the latest Maastrichtian Stage (latest Cretaceous) and Danian Stage (Early Paleocene). In the supergene enrichment zone of the area, the original sulfide mineralogy has been altered.
Seen here are weathered rocks at the southern edge of the Berkeley Pit (Berkeley Mine), a huge open-pit copper mine that closed in 1982. I saw this site in 1991, 2010, and 2011. The water level has been slowly rising each year and is approaching the level of the area's water table. If water levels reach the same elevation as the aquifer, polluted water from the pit will drain into surrounding areas. The Berkeley Pit's water is iced tea-colored. The water filling the mine comes from about ten thousand miles of flooded underground mine tunnels. Dewatering of the Butte area by water pumps allowed operation of these deep mines, until they were turned off by the Anaconda Copper Mining Company in 1982. Dissolved oxygen in the water in the flooded mine tunnels oxidized sulfide minerals in the rocks, resulting in acidic and heavy metal-rich water - this is why the Berkeley Pit lake is polluted. Oddly, the water is rich enough in copper that the water is mined! Water is pumped out, copper is precipitated out, and the used water is returned to the pit.
The environmental nightmare at Butte, Montana was made worst by politicians. A proposal to push mine waste rocks into the Berkeley Pit would have prevented the pit's water from becoming so acidic - the waste rock tailings are high pH (about 10). Politicians refused, creating a worse situation. The lesson here is to NEVER, EVER, EVER let politicians make scientific decisions. They're all bone-headed morons.
When I visited in 2010, I obtained the following Berkeley Pit water analysis from the Montana Bureau of Mines & Geology: 64 parts per million (ppm) copper, 500 ppm zinc, 0.1 ppm arsenic, 500 ppm iron, 200 ppm manganese, and a pH of 2.5 to 2.7 (= cranberry juice). The acidity value varies with season and sample depth in the water.

Machine (along with sister machine) was purchased to replace 2 Cat 5130's which originally belonged to Bridgetown Plant.
The Cat's were parked up for some time and incurred a lot of downtime through burst hoses etc. The 5130's received a lot of negative press due to early hour reliability. Most problems were sorted when the larger B series came out, unfortunately for Cat the damage had already been done by that time and a sour taste had been left.
The 5130's were sold to Hoss Equip in Texas and the Demag's worked steady for many years. The site has since closed and the machines will be sold on.

Eric Fisher was a prominent Winster man during my 1950s childhood. He was also active in village life. In the late 1940s he lived with his family at Mount View, West Bank, quite near where my family lived on The Flat. Later on both our families were neighbours on Leacroft Road.

Pyramiden (Danish, Norwegian and Swedish meaning "the pyramid", Russian: Пирамида, piramida) was a Russian settlement and coal mining community on the archipelago of Svalbard, Norway. It was founded by Sweden in 1910, and sold to the Soviet Union in 1927.
It lies at the foot of the Billefjorden on the island of Spitsbergen, and is named for the pyramid-shaped mountain adjacent to the town. The settlement once had a population of over 1,000 inhabitants, but was abandoned on the 10th of January, 1998 by its owner, the state-owned Russian company Arctikugol Trust. It is now a ghost town. Within the buildings things remain exactly as they were when the settlement was abandoned in a hurry.
There are no restrictions on visiting Pyramiden. However, visitors may not enter any buildings without permission, even if the doors are open, due to the health and safety hazards involved. Most buildings are now locked. Pyramiden is accessible by boat or snowmobile. Guided tours are available in Russian, Norwegian, and English.
The nearest settlements are Svalbard's capital, Longyearbyen, some 50 km to the south, Barentsburg approximately 100 km south-west and the small research community of Ny-Ålesund, 100 km to the west.
It is predicted that due to the low rate of decay in a frigid clime, the abandoned town's major buildings would be visible 500 years from now.
Pyramiden is currently being re-developed by the Russians to accommodate tourists. 5-6 people are currently stationed there to upgrade the facilities.

It's hard to describe how we felt when Pyramiden town appeared and became more and more visible as our boat approached its port.
Ghost city that plays strong with one's emotions - no matter if you remember Bradbury's books and Cormac McCarthy's The Road, or any of B-movies dealing with post-apocalyptic scenarios.
We were extremely lucky - when all the tourists were going back to the boat after a few hours visit, leaving us in Pyramiden alone, the guide told us that the two most beautiful days of Spitsbergen summer were just forecast. He was right - and the 2-nights stay there gave us unforgettable memories.
The three major manufacturers of off-highway mining trucks are Caterpillar, Komatsu, and Terex. Komatsu and CAT trucks I've seen elsewhere, but this was my first look at a Terex.
Terex at one time was owned by General Motors, but is now an independent company. That is a good thing because GM has fallen on pretty hard times of late.
This particular truck is an MT 3000 series truck with a hauling capacity somewhere between 150-200 tons (about the same as the CAT and Komatsu trucks here).
