Mining hoist

Mine hoist is the main transportation equipment that connects the underground and the surface in mining engineering, mining engineering. Mine hoist is a hoisting machine installed on the ground, which drives the hoisting container along the shaft or ramp with the help of steel wire rope. It is used in vertical shafts and inclined shafts to lift coal, ore, gangue as well as to elevate and lower personnel, materials, tools and equipment.
Sometimes called mine elevator, mine hoist is a special form of elevator, which can also be regarded as a kind of simple elevator. In the project of conveying people and things in the mine, the mine hoist is a very important conveying tool. Mines, especially underground conditions and working environment compared with the ground on the ground, is relatively harsh, so it is necessary to ensure the safety of mine elevator, must carefully understand and master its structure, working characteristics and design methods and a series of issues. China's production of the main structural forms are: single-rope winding type has a single cylinder and double cylinder mine hoist; friction type has a multi-rope floor type and tower multi-rope friction type hoist. Drag mode is designed according to the needs of the other for underground hydraulic drive mine hoist. China's commonly used form of mine hoist is mainly single rope winding type and multi-rope friction type. China's mines and the world's mining industry is more developed countries, compared with the mining of smaller wells, mine hoisting height is shallow, coal mine with more, other mines (such as metal mines, non-metallic mines) is less, in addition to the proportion of inclined shaft hoisting accounted for quite a lot. Therefore, in the 1960s, the single rope winding mine hoist is used more, because the single rope winding type is more suitable for this kind of mine.
