Introduction. For years, Alpha has provided innovative solutions to all facets of ore handling in underground mining operations. Alpha always cares about the safety and efficiency of underground mining, no matter in inclined shaft, or in vertical shaft. The mine hoist (winder) is wildly used in coal mine, metal mine and non-metal mine.
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 the hoist motor mounted on the ground). The headframe will also typically contain bins for storing ore being transferred to ...

Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It …
Apr 08, 2017· The gear shaft was lifted out of its bearings, and replaced by another, geared to a 112-h.p. alternating-current motor. It has since been replaced by an electric hoist driven by a 225-h.p. alternating-current motor. It hoists a double-deck cage at 800 …
Jun 06, 2018· As a key component of a mine hoist system, the main-shaft device bears most of the bending moment and torque. Thus, it is important to quantify the performance of the main-shaft device and ensure the reliability of the device. The paper aims to investigate the impact of uncertain structural parameters on the reliability of the main-shaft device. The probabilistic optimal design is performed ...
Mar 12, 2017· Yorke hoist – a hoist mounted on a vertical pipe, stayed by wires from the top, enabling free movement of the hoist mechanism around the mine shaft. Using a hoist is generally a two person job. A bucket of mullock from deep inside a mine shaft can be hoisted to the surface, swung away from the shaft and emptied by an operator at the surface.

"RUDNA" MINING PLANT BRANCH Zakłady Górnicze "Rudna" ("Rudna" Mining Plant) is one of the three branches of KGHM Polska Miedź S.A. – a global leader in mining and processing copper, precious metals (gold and silver), molybdenum and rhenium.
The two systems have a 5.7 m dia., a payload of 45 t and an average payload of 1530 tph. They are now used in the main shaft for the Majialang coal mine, significantly improving operational efficiency. More recently, they have won the order to supply four new mine hoists to the Balasu coal mine project.
The shaft house, or as it is known locally, the "Quincy No. 2 Rock House," was built above one of the inclined shafts through which the Quincy mine raised the ore to the surface through its No. 2 shaft. The mine has been inoperative since 1945. The shaft house has three purposes: (1) to provide a building for a crusher to break up
Friction hoists or Koepe hoists are the second main type of hoist. Instead of a drum located some distance away for the shaft, as in drum hoisting, the drum is directly above the shaft itself. Rope passes over the wheel during hoisting operations. This type of hoist is synonymous with low initial capital cost and high reliability.
