Bell Pit Mining. Bell pit mining was one of the early methods of underground mining. The name comes from the shape that the mine forms. A long narrow shaft is dug down until it reaches the coal seam. Once it reaches the seam, the coal is then mined laterally along the seam either side of the shaft, creating the bell shape. The coal would then be wound up to the surface in a similar way to getting water out of a
And in the early years, coal was mined entirely by hand. Miners usually worked in pairs to undercut, pick-axe, drill, and blast the seams in order to break coal pieces free. During the 1880s, mechanical coal cutters began to be introduced into some mines, making the job a little easier and a lot more efficient.
Another method of mining were drift mines which were usually sunk into the hillside. The coal seam was usually visible at the side of the hill (known as outcrop coal ), the coal was first removed from the side of the hill, then the miners had to follow the seam further and further underground, the coal was worked until the working conditions became unsafe. The mine was then abandoned.
The conventional mining techniques described above, made up of the cyclic operations of cutting, drilling, blasting, and loading, developed in association with room-and-pillar mining. The oldest of the basic underground methods, room-and-pillar mining grew naturally out of the need to recover more coal as mining operations became deeper and more expensive. During the late 1940s, conventional techniques
Changes evolved through a need to make a safer underground environment for the thousands of miners employed in Cape Breton’s coal industry. It has been said that perhaps the most beneficial development in mining equipment was the methanometre, an instrument used
These early methods were not efficient, and it was not yet possible to dig up much coal from the Earth. But this was still a very significant step in the history of coal mining. Small scale shaft mining was first tried out, and this would provide the prototype for future methods. Drift mining and belt pits were also commonly used to begin with
During the early years of the Alberta coal industry, mining usually involved small-scale operations under varying degrees of danger, in difficult conditions, and for long hours. And in the early years, coal was mined entirely by hand. Miners usually worked in pairs to undercut, pick-axe, drill, and blast the seams in order to break coal pieces free. During the 1880s, mechanical coal cutters began to be introduced into
Over the past 250 hundred years, the coal mining industry has witnessed significant changes to both its mining techniques and the equipment used throughout the mining process. Changes evolved through a need to make a safer underground environment for the thousands of miners employed in Cape Breton’s coal
Early coal extraction was small-scale, the coal lying either on the surface, or very close to it. Typical methods for extraction included drift mining and bell pits. In Britain, some of the earliest drift mines (in the Forest of Dean) date from the medieval period.
Coal was first exploited by underground mining methods in Cape Breton in 1720, with the French Port Morien mine supplying the fortress of Louisbourg. Annual production of Nova Scotia coal increased with expanding industrial output, from just over one million tonnes in
The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7)
Brief History of Coal Mining in Illinois. Observations by early explorers of coal outcrops along the Illinois River took place in 1668, 1669 and 1673. Coal mines in the early 1800s consisted of outcroppings of coal seams along the bluffs of rivers and streams. By some accounts the first commercial coal mining took place in 1810 along the banks of the Big Muddy River near Murphysboro in Jackson County. U
