Prospecting for gold with drilling rig
Clips of a small rig drilling prospect holes in advance of a gold-mining dredge at either the Coal Creek or Woodchopper Creek historic mining camps, located in what is today the Yukon-Charley Rivers National Preserve in eastern Interior Alaska. By drilling and testing for gold concentrations at regular intervals, a map could be made of an entire creek valley. This map then allowed gold mining companies to aim their giant dredges toward the highest concentrations of gold (Color/Silent/16mm film). This sequence contains excerpts from AAF-138 from the Cordle collection held by the Alaska Film Archives, a unit of the Alaska and Polar Regions Collections & Archives Department in the Elmer E. Rasmuson Library, University of Alaska Fairbanks. For more information please contact the Alaska Film Archives.

The Largest Oil Rig in The World
Perdido is the deepest floating oil rig (platform) in the world at a water depth of about 2450 meters operated by the Shell Oil Company in the Gulf of Mexico. The Perdido is located in the Perdido fold belt which is a rich discovery of crude oil and natural gas that lies in water that is nearly 8000 feet deep. The platform's peak production will be 100,000 barrels of oil equivalent per day. At 267 meters, the Perdido is nearly as tall as the Eiffel Tower. An oil rig is a large structure with facilities to drill wells, to extract and process oil and natural gas, and to temporarily store product until it can be brought to shore for refining and marketing. In many cases, the platform contains facilities to house the workforce as well.

Blasthole Drill Mining Training Simulator
The Joy Global Blasthole Drill Mining Training Simulator is available exclusively from Joy Global. Visit Joy Global for more details: http://www.phmining.com/en/PHMining/Training/ProMinerTrainingSimulators.htm This 3D simulator increases your bottom line by producing an extremely well-trained workforce with operators who quickly become experts at the controls of blasthole drills. This allows them to preform their jobs faster, safer, and more efficiently. http://forgefx.com/casestudies/surface-mining/blasthole-drill-simulator.htm Realistic virtual training simulators allow operators to learn the machines quickly and safely, as well as master the entire process from start to finish before they ever step foot into a real-world piece of machinery. Training simulators lead to less machine downtime, fewer accidents, and a more efficient and productive operation. The simulator features beginner and experienced modes, so that operators at different levels can benefit by using the training simulator to increase their skills. In addition, a tutorial mode is included for users that are new to virtual training simulators. Tutorials provide step-by-step instructions to operators on how to preform basic drill functions, such as how to raise the mast, how to drill a hole, and how to assemble the drill pipe string. Connected to a pair of real-world controllers, the simulator mirrors the real-world equipment, allowing the operator to learn everything from operating the breakout wrenches, to the pipe racks, to the bit-air system. The time-of-day feature allows operators to learn to use the drill in a variety of limited light conditions, while the local and remote propel modes allow operators to train to operate the drill from inside, or outside of the cab. At all times during the simulator session real-time performance data is being collected and tracked, everything from session time, to drill bit depth, to rotary RPM. The simulator allows operators to monitor themselves in real-time, and it also generates a performance report at the end of the session that provides greater insight into an operator's performance by listing everything from setup time, to number of regrinds and over-currents. By leveraging this data, operators can optimize their productivity within the simulator where they have the freedom to experiment with different techniques. The bottom line is that the Joy Global ProMiner Blasthole Drill Simulator, while emphasizing safety, is designed to maximize operator machine controls and operation familiarity, efficiency, and productivity.

High efficiency electric drive down the hole drilling machine for mining projects
DTH drilling equipment are used extensively in construction sites such as open pit and underground mines, quarries, hydropower projects, water well drilling, mineral exploration, rock cable anchoring, geothermal excavation, subway engineering excavation side pile support. Because of the advantages of high drilling rigidity, smooth hole wall, good rigidity of drill pipe and impactor, independent of high axial thrust, unrestricted drilling depth and low equipment investment, it is easy to maintain and so on.
