Churn Drill
The churn drill is a large drilling machine that bores large diameter holes in the ground. In mining, they were used to drill into the soft carbonate rocks of lead and zinc hosted regions to extract bulk samples of the ore. Churn drills are also called percussion drills, as they function by lifting and dropping a heavy chisel-like bit which breaks the rock as it falls. Churn drills are most effective in soft- to medium-density rock of relative shallow depth (10–50 metres). History Churn drills were invented as early as 221 BC in Qin dynasty China, capable of reaching a depth of 1500 m. Churn drills in ancient China were built of wood and labor-intensive, but were able to go through solid rock. The churn drill appeared in Europe during the 12th century. A churn drill using steam power, based on "the ancient Chinese method of lifting and dropping a rod tipped with a bit," was first built in 1835 by Isaac Singer in the United States, according to ''The History of Grinding''.

Drill
A drill is a tool used for making round holes or driving fasteners. It is fitted with a drill bit for making holes, or a screwdriver bit for securing fasteners. Historically, they were powered by hand, and later mains power, but cordless battery-powered drills are proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, and utility projects. Specially designed versions are made for surgery, dentistry, miniatures, and other applications. History Around 35,000 BC, ''Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tools
A tool is an object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early human tools, made of such materials as stone, bone, and wood, were used for the preparation of food, hunting, the manufacture of weapons, and the working of materials to produce clothing and useful artifacts and crafts such as pottery, along with the construction of housing, businesses, infrastructure, and transportation. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The introduction of widespread automation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pine Point Mine
The Pine Point Mine is located on the south shore of Great Slave Lake between Hay River to the west and Fort Resolution to the east, in the Northwest Territories of Canada. It produced lead and zinc ores from a Mississippi Valley Type deposit between 1964 and 1988. Most of the mining was done by open-pit methods. The town of Pine Point was built by the mining company, Cominco, and when the mine closed the town was abandoned and demolished. History The Pine Point ore deposit was discovered in the late 19th century by fur traders at Fort Resolution who learned of the lead ores from the First Nations. A minor staking rush occurred in 1898 when Klondike prospectors heard rumours of silver at the location. There was no silver to be found, and although the lead ore was very rich, it was not feasible to mine the isolated deposit without good transportation to the south. The first major exploration work was done in 1928–1930 when several short shafts were sunk and a churn d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fort Smith, Northwest Territories
Fort Smith ( "beside the rapids") is a town in the South Slave Region of the Northwest Territories (NWT), Canada. It is located in the southeastern portion of the Northwest Territories, on the Slave River and adjacent to the Alberta border along the 60th parallel north.

This route allowed its users to bypass the four sets of impassable rapids (Cassette Rapids, Pelican Rapids, Mountain Rapids, and Rapids of the Drowned). The Portages in North America, portage trail had been traditionally used for centuries by generations of local Indigenous peoples in Canada, Indigenous peoples.

Tri-State District
The Tri-State district was a historic lead-zinc mining district located in present-day southwest Missouri, southeast Kansas and northeast Oklahoma. The district produced lead and zinc for over 100 years. Production began in the 1850s and 1860s in the Joplin - Granby area of Jasper and Newton counties of southwest Missouri. Production was particularly high during the World War I era and continued after World War II, but with declining activity. As jobs left the area, the communities declined in population.
