What is shaft mining?
shaft mining - also referred to as a sinking shaft - is a type of mining process used to vertically access the underground mining equipment. There are many different components that form a shaft, all of which play a very important role in the mining process. Entry to the shaft can pass different names, depending on whether the entry is above or below the ground. If above the ground, it is commonly referred to as a shaft or portal; If the entrance is underground, it is known as Winze. However, Winzes is only used in shaft mining only for connecting the lower parts of the mine. Like the tree, the service cages will have several branches that reach from it. These branches pass through various names such as levels, drift or gallery. The area at which the level meets the service cage is known as the shaft station or Jánset. Each level is perpendicular to the service cage, allowing the horizontal access path to the ore body.
In most shaft mining procedures, the shaft will be divided into different sections. Each section is vertical because it runs parallel to a service cage. In most of the shaft down, most of these sections are used for lifting purposes. The service cage itself usually contains a large elevator that is used to transport the mining staff up and down the shaft to different levels. The sections usually have a rectangular shape and are lined with either wood or concrete.
In addition to the service cage, small shafts are known as skipping. Shaft mining often requires the use of at least one skip because they are used to transport ore to the surface. It is a basically smaller version of the service cage and usually bears staff. Skipping can also be used for other needs such as pipe and fuel along with ventilation systems. These are all very necessary parts of shaft mining, because water, fuel and air play an extremely important role in maintaining the mine - and its workers - fully operation.
on the surface of hlAva uses for reels up and down the shaft. This is done using a jack, which is usually connected to the Sheave wheel. The head frames were once built of wood, but the requirements for strength and reliability led to steel and concrete framing. Another role played by the head frame in shaft mining is the provision of storage for ore.
