A pinion shaft for the mining industry. Just putting the finishing touches on the spines on our HoĢfler 8000.
The Blue Bird Mine was intermittently active for more than 90 years before closing permanently to mining in the early 1960s. In between active mining periods, the complex -- which sits near the edge of a quiet meadow with expansive views -- became a favorite "whistle stop" for tourists visiting the mountains on the Switzerland Trail Railroad in the early 1900s.

The mining industry is a potential threat to Sumatran orangutan habitat in a number of important areas, both directly by its own activities and indirectly by road access. It includes a major gold mine near the town of Batang and iron ore mining in the Alas valley, and planned development of coal mining in the hill forests inland of the Tripa swamps.

On our scenic drive through the mountains, we stop in the small town of Nederland to grab lunch and a pint. We pass by a mining museum with aging machinery rusting in peace outside. I enjoyed taking a few pictures after lunch before heading back to Denver.

Audrey Headframe Park
Jerome, Arizona
Largest wooden headframe still standing in Arizona, it was completed in 1918 to haul ore up from the mine. Shaft is 1900 feet deep, concrete lined with cross tunnels every 100 feet to Edith shaft. Edith shaft headframe was completed in 1915 to haul men and supplies. A wooden structure, it was torn down in 1981 and replaced with the steel version you see today, 260' to NW.
Between 1915 and 1938 almost 4 million tons of ore was extracted from the mine, producing 397,000 tons of Copper, 221 tons of silver and 5.5 tons of gold. Ore was brought to the surface then transported by tram and burro train, to the railhead in the valley. Later, ore was taken out underground through the Josephine tunnel, which was 1300 feet down and 2.5 miles long.
A coal preparation plant (CPP) is a facility that washes coal of soil and rock, preparing it for transport to market. A CPP may also be called a "coal handling and preparation plant" (CHPP), "prep plant," "tipple," or "wash plant".

According to the historic gold museum in Dahlonega, the gold found in North Georgia is considered to be some of the worldās finest, with a purity content of about 98%, higher than that later found in both California and Alaska. Because of this purity, mining was an integral part of Dahlonegaās economy and culture for many years. Mining started after Benjamin Parks found gold in 1828. However, as the years passed by, it became harder and harder to find the precious metal in streams and shallow digging. New ways to mine were developed, including digging deep mines into the mountains and using high-powered water cannons (like the one shown here). Hydraulic mining (using water cannons) wore down the mountain so that the miners could get to the gold ore; hydraulic mining, unfortunately, left huge, ugly gashes in the mountainsā sides.
Information found in the historical film shown at the Dahlonega gold museum shows that mining in North Georgia continued through the 1900s. In fact, in the 1930s, the mining business struck their wealthiest findings that ever the mines had produced. Graham DuGas, owner of the Calhoun mine, made a fortune in the early 1900s in the gold industry. However, the mines were all abandoned during World War II, when the men left to go fight.

Last used around 1873 at Island Mine, Isle Royal. I was amazed at how well preserved this machine is.

Arigna miners would lie on their sides in this space which was often water-logged. And then there were the rats...
Sand Mining---Sand mining activities, a tradition spanning many decades, in Tugumukti village, Cisarua, Bandung, West Java, Indonesia, 7 September 2011. The hills of Cisarua hold great potential as their sand is of very high quality, so much so that illegal mining activity is threatening the destruction of the ecosystems of the hills. Seeing as it is their only means of income, something must be done to prevent any further illegal poaching from occuring.

A coal mining risk assessment is a well-established procedure for determining whether a devel-opment site is in a high-risk area. It requires validating plan proposals for non-householder and commercial planning applications in a high-risk area for development proposals.
The coal mining risk assessment includes an assessment of the Coal Authority Mining Report. Also, a visit to the offices of the Coal Authority to assess mining plans, a review of modern and historical published geological maps, and a review of technical reports/memoirs. The other pur-pose of a coal mine risk assessment is to identify coal mine risks at the development site and de-velop a plan to ensure the safety and sustainability of the development site. Earth Environmental & Geotechnical's experienced team immediately revises your mining risk assessment. For more details kindly visit- www.earthenvironmental.co.uk/coal-mining-risk-assessment/
