According to the Bureau of Labor Statistics, the mining industry consists of five major segments: coal mining, gas and oil extracting, metal ore mining, nonmetal mineral mining and supporting activities such as resource transportation. Each segment requires the use of specific equipment, but there are several types of mining equipment that are
Tools of the Trade. This part of the collection covers a whole range of objects, from small gas detectors to large industrial machines, which were used both above and below ground in the coal mining industry. The collection is particularly strong in twentieth century coal cutting machines, rescue equipment, surveying equipment and miners' lamps.

Article: (Bulgaria c. 3,000 BC) Thousands of uniformly 'pressed' gold 'beads' were discovered in a Thracian horde in the Bulgarian 'Valley of the Kings'.The beads, which are only millimetres in diameter, have the appearance of minute 'washers', which show evidence of 'pressing' on both sides.
Infographic: History of Metals Timeline. The development of civilisation has relied heavily on the discovery of metals. Prehistoric man used metals to build tools and weapons and as our knowledge of metallurgy has developed, metals have played an essential role in the advancement of agriculture, transport and arts and craft – forging the path to today's modern society.
Do we need metal for mining metal? Humans have had a long history of nonmetal tools. Wood and stone may not seem like a good choice, but the two could (and were) used be for millenniums for tools for farming and other work. Less expensive wooden p

The methods used to loe ore bodies range from ontheground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.
2020417&ensp·&enspThe early mining of iron ore in Minnesota was carried on with the most primitive kind of tools. The pioneers used only such equipment as could be packed from Duluth through one hundred miles of forest to the first mines on the Vermilion Range and the operations were carried on with picks, shovels, hand drills and wheelbarrows, the ore being hoisted in buckets with a horse winch and carted in

Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th
Up to the 18th century coal was only mined near the surface beside outcrops, this type of mining was known by the names, "bell pits" and "adit mines". Monks at various places, including, Culross, Dunfermline, Newbattle, and Edinburgh, were digging in bell pits and open cut mines as early
