The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

9. PURPOSE OF SHAFT SINKING shaft sinking is used for many purposes. To transport men and materials to and from underground Workings. For hoisting ore and waste from underground. To serve as intake and return airways for the mine (ventilation shaft). To access an ore body These shafts are used in applications such as hydro electric projects, water supply, …
Learn about shaft mining, a form of underground mining where shafts are pushed vertically to excavate ores and minerals. Find out how shafts are sunk, lined, compartmentalized and used …
Mining - Drifts, Tunnels, Shafts: All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exploration. A drift running parallel to the ore body and lying in the footwall is called a footwall …
Shaft mining is an excavation method used to access an underground ore body from the top down. The term "shaft" refers to the vertical tunnels sunk underground for mining and engineering projects.. When the opening starts on the surface, the resulting tunnel is called a shaft. If the vertical tunnel starts underground and pushes upward, it's called a sub-shaft.
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes …

A rectangular shaft sunk in recent years is the main shaft at Mochia Magra Mines, Zawar, Rajasthan (Hindustan Zinc Limited). It is of 5.2 m x 3.8 m in cross-section, vertical, 321 m deep from the shaft collar with 30 cm thick concrete lining. Shaft sinking is costly operation. The mining companies pay to the shaft sinking contractors
Usually, skip shaft is used for a large mine, and cage shaft for a small mine. Depending on the location of hoist, the arrangement of hoisting equipment in main shaft can be tower arrangement (Fig. 1) or floor-supported arrangement (Fig. 2). Fig. 1.

In these cases mine shafts go vertically down and side tunnels make it possible for the miners and equipment to reach the ore. A structure called the headgear is constructed above the shaft and controls the lift system into the vertical shaft. ... Look at the beginning of the chapter for a generic flow diagram for mining. Use the following ...
4. What shafts do Shafts, being links between pit-top and pit-bottom, have several important jobs to do: 1.WINDING -Providing ways for coal to be raised. -Providing ways for men to be lowered and raised. -Other winding (Supplies, machines, ponies etc.) 2.PUMPING -Holding pipes for water which is pumped out of the mine for disposal.
