of all the evolutions in coal mining over the last few centuries, none is more significant than technology. In the early days, coal was mined by hand, with individuals wielding a pick and shovel. By the Industrial Revolution, coal-cutting machines and steam shovels designed for coal mines were common, making the work more efficient. And throughout the 20th century, improvements in equipment design led to dramatic increases in productivity and safety. Today, new advances in technology are driving even higher levels of performance and material management-especially in open-pit, or surface, coal mines, where miners are focused on removing the most material as quickly and safely as possible. As dragline operators work to extract coal, for example, they can simply glance at an in-cab display that shows the position of the bucket and tub relative to the design plan, as well as whether each dig point is above or below plan. That helps them move material accurately and efficiently. Machine health data is also available in the cab, so operators can identify potential problems-like tilt due to an unstable pad-and act quickly to prevent failures. Likewise, production monitoring tools provide site planners with real-time information on dragline activities, right down to individual bucket loads and dump locations. By monitoring performance, productivity and payload, they can optimize dragline output and minimize operating costs. Some mines are even using this type of information for teaching purposes-identifying operators who need additional training and helping them understand how variations in operating practices can affect dragline production and material management.
When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable. To become steel, it must be melted and reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. This liquid is then continuously cast into long slabs or cast into ingots. 96% of steel is continuously cast, while only 4000 ingots are cast per year. The ingots are then heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. In modern foundries these processes often occur in one assembly line, with ore coming in and finished steel coming out. Sometimes after a steels final rolling it is heat treated for strength, however this is relatively rare. Hope this helped
In the 1880s, common mining jobs included coal miners, gold miners, silver miners, and copper miners. These miners worked underground or in open-pit mines extracting various minerals and ores. The job roles in the mines often included laborers, drillers, muckers, and pit bosses.
pit ponies were shetlands or small hardy ponies that were used in the pits, or mines. they carried tools and coal and things for the miners.

Gravel Pit?!? "Check out my gravel pit A mystery unraveling"
Silicosis is caused by fine rock dust trapped in the lungs. It is found in hard rock miners and also open pit miners also anyone exposed to fine rock dust in the air on a continual basis.
yes, 14 was killed 8 injured the cause was found to be a electric lamp that sparked and caused a explotion

There are areas that has insurance of 100,000 dollars. Check your area law on pit bulls.
like strip mining open-pit mining involves removing the surface layer of soil. Miners then use explosives to break up the underlying rock and recover the ore. As they dig a deep hole or pit to mine the ore they build roads up on the sides of the pit. Trucks carry the ore to the surface. Ores of copper and iron are obtained by open-pit mining.

stick it under your arm pit. ;)
