shaft mine: types of mines
The diagram depicts a cross section of three different kinds of mines, along with structural elements of the underground shaft and slope mines. The shaft mine has compartments for a skip hoist, elevators called cages, and service facilities such as ventilation ducts. In a slope mine, the miners also work at different levels, and the ore is sent to the surface in bucket hoists.

How gold is made
Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 , when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry, religious artifacts, and utensils such .

Gold Magic
Using the latest in computer aided design and engineering, Gold Magic has made significant changes to the original style gold pan. It is the first major change in the gold pan in 4,000 years! We have coupled the patented spiral gold pan with a high tech, portable power unit, making gold panning automatic. Now anyone can become a pro at gold mining.
Bitcoin Energy Consumption Index
Because of the aforementioned scalability issues, it's often argued that Bitcoin is more like "digital gold" than a payment system. Hence we can also compare Bitcoin mining to gold mining instead. Every year, around 3,531 tonnes of gold are mined, with a total related emissions amounting to 81 million metric tonnes of CO2.
