In underground mining a hoist or winder is used to raise and lower conveyances within the mine shaft. Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (thyristors), however modern large hoists use alternating current drives that are variable frequency controlled. There are three principal types of hoists used in mining applications:
2019-01-01 INTRODUCTION The mine hoisting plant is the most critical single line component in the operation of a shaft sinking operation or a permanent installation. Bad decisions in the design and selection of the hoist plant equipment can significantly add to the operating costs and up-time in the operation of the mine.
Mine Shaft Systems has over 100 years of design and installation experience, having installed over 500 hoist systems. We have both designed and manufactured more Blair Multi-Rope hoists than any other hoist supplier. We are also the first company to successfully design and deliver a hoist with a winding depth of 3150 meters.
Nonetheless, mine shafts featured prominently as well, with some excellent presentations provided on both design and construction aspects of modern deep-shaft development. In addition, the organizers accepted a couple of papers that, rather than looking specifically at shaft-sinking issues, reported on the overall development of China’s coal industry, in the context of the shaft-sinking ...

When it comes to design of a mine shaft, there are two options: circular shafts and horizontal shafts (Figure 1, Figure 2). Circular shaft is the most commonly used one. If the shaft should be deep and shaft diameter is supposed to be more than 4.5 meters, circular shafts are the best choice.
The most visible feature of a traditionally-built mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist used, the top of the headframe will either house a hoist motor or a sheave wheel (with
