Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel 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 refers to shallow shafts and it is different from a deep shaft. The former is sunk for the civil engineering projects and the latter is sunk for the mining projects. When the excavation is done on the ground surface, it is called a shaft and if it is on the underground it is called a sub-shaft. This is also known by the name Winze.
These books detail many different mining methods used in German and Saxon mines. A prime issue in medieval mines, which Agricola explains in detail, was the removal of water from mining shafts. As miners dug deeper to access new veins, flooding became a very real obstacle. The mining industry became dramatically more efficient and prosperous
In 1880-1905, a “Second Gold Rush” in California was based on industrialization and returning miners, new investors and improved deep shaft mining technology which was applied to older mines, pursuing new veins associated with the revised mines earlier abandoned. Electricity, steel stranded cables, square set timbering, water and

The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today.
In slopes and shafts natural drainage is impossible, and the waters of the mine must be pumped or lifted out by steam power. Andrew Roy, The Practical Miner's Companion; or, Papers on Geology and Mining in the Ohio Coal Field (Columbus: Westbote Printing Company, 1885): 97

between 1850 and 1900 would not have been possible. One of those constraints was ambient explosive gas. In this paper we consider a particular kind of new process technology in coal mining, mechanical ventilation, that aimed to solve the problem of methane. As mines descended deeper and into previously unexploited basins, miners encountered
The Dangers of Coal Mining in the 1800's The mines back in the 1800’s were not built like they are today. In fact most of the smaller mines back then didn’t have tunnels leading into the mine, but a shaft instead. The shaft was a hole blown into the mountain that went straight down. These were deep
Coal mines in the Industrial Revolution were deeper than ever before. Before the 18th century, coal was mined from shallow mines. However, as the Industrial Revolution gained speed, demand for fuel rapidly increased. Before the Industrial Revolution, there were two different types of mines: bell
16/09/2011· There is some history that suggests the first deep shaft in Rowley Regis, was sunk about 1794, but other mines around the region had already come and gone, and were in operation long before this. Not many of the early Mines were recorded, which later on would cause great loss of life, and so it's impossible to say for certain, how, or if

The Kennedy Mining Company was formed in 1860 when he and three partners began digging shafts near today's mine property entrance. The mine operated sporadically until it closed in 1878. In 1886 fifteen people invested $97,600 to reopen the mine under the corporate entity of the Kennedy Mining and Milling Company.
The Gympie Gold Story: Exploring and Reopening A Historic Goldfield In Today's Business Reality. Ron Cunneen 1 & Ian Levy 2 . ABSTRACT. Australia was built on gold and from 1850 until 1950, most of the gold came from reef orebodies in the historic goldfields of Eastern Australia.
For three days between 19 and 21 February 1882, the people of Trimdon Grange and Kelloe buried 74 people. Some were buried in mass graves. Others were laid to rest in a cemetery a few miles away. Most people in Trimdon Grange buried someone in their family. Many of the dead left behind young
Although some deep mining took place as early as the late Tudor period (in the North East, and along the Firth of Forth coast) deep shaft mining in the UK began to develop extensively in the late 18th century, with rapid expansion throughout the 19th century and early 20th century when the industry peaked. The location of the coalfields helped
From around 1750 to 1850, the Industrial Revolution changed life in Britain. It was a very important period in British history. During this time, factories were built, to produce goods such as textiles, iron, and chemicals on a large scale. The steam-engine was invented, which could do more work than men or animals, and canals and railways were

Coal mining is a term that encompasses the various methods used to extract the carbon-containing rock called coal from the ground. Coal tends to exist in seams, which are lateral layers under the earth that may vary in depth from one or two feet to dozens of feet.
A Nation Divided: The Political Climate of 1850s America By the 1850s the United States had become a nation polarized by specific regional identities.

Tonkin's shaft was also extended and all stopes looked well. With a steady production at the mine the town of Callington expanded and several new buildings were added in 1864, including the prominent Ising store. Production declined during the next years even though the main shaft had reached a depth of almost two hundred metres. While at work
