9/21/2020· The original Mine Hoist Problem was posted 25 August 2020, and the first Hint was given on 8 September. We are now almost one month into this problem, and thus far no one has sent me even so much as a question other than Tim Dennison's request for a video.
A mining hoist (also known simply as a hoist or winder) is used in underground mining to raise and lower conveyances within the mine shaft. It is similar to an elevator, used for raising humans, equipment, and assorted loads. Human, animal and water power were used to power the mine hoists documented in Agricola's De Re Metallica, published in 1556.
Mine hoisting systems at Longgu Coal Mine Safe and reliable production In 2004, Xinwen Mining Group, one of the ten largest coal mining enterprises in China, awarded a significant contract to ABB for two production hoists for Longgu Coal Mine, the first of seven coal mines to be developed in Juye mining area, Shandong Province.
The BMR hoist was invented in 1957 and was a significant improvement to hoisting systems. The invention of the BMR hoist began with Robert Blair’s idea to combine the flexibility of the drum hoist with the large load capacity from the multiple ropes in the friction hoist system.
Safety Plus Hoist Monitor (SPHM) is the world’s first mine hoist safety monitor designed in accordance with IEC62061 international functional safety standards (Safety of Machinery) and achieving Safety Integrity Level 3 for the majority of its safety protections (SRCFs).

• First you will need to go to Formorgar Mines. At east side of the entrance ramp, you will see the Hoist. Hoist is a kind of elevator like that one in kazordoon, but with teleports: Archivo:Mines entrace.jpg • At the 1st floor you will face only Novice of the Cults, Gargoyles and Mammoths. Just keep following the blue line until you reach a ramp. • Now you are at the 2nd Floor. Going
This 5.7 x 2.2-m, electrically coupled Blair multi-rope (BMR) man/material hoist at AngloGold Ashanti's Moab Khotsong gold mine in South Africa was the first hoist to operate to a depth of 3,150 m in a single wind, with an end-load of 23 mt. (Photo courtesy of FLSmidth)

A premier destination that tells the amazing story of Michigan's copper mining era, a forgotten part of our national heritage. The Quincy Mine Hoist Association preserves and interprets the history, landscapes, buildings, and industrial work experiences of the Quincy Mining Company, educating people about Michigan’s significant copper mining heritage.
ABB has secured a A$24m ($17m) contract to provide mine hoist systems to Newmont’s Tanami gold mine in Australia. ABB will be responsible for the design, supply, installation and provision of long-term services for the entire mine hoist mechanical and electrical systems for the mine
First, the basic parts of a mine: you always refer to a mine as if you are facing into it. The part of the mine you are working to drill, load, and blast is called the “face.” The left-side wall is the “left rib” and the right-side wall is the “right rib.” The ceiling is the “back” and the floor is the “foot.”
Fig 7: Equivalent Stress 6. CONCLUSION This paper presents the study of the design and optimization of Central Drum in Mine Hoist. As we see the central drum in mine hoist is large and heavy for manufacturing and installation and to rotate full body with loads. The study gives the new design which can reduce the weight of central drum.
