Costs of sinking a mine shaft vary with the size and depth of the shaft nature of the rock the ease with which it can be drilled and broken, and the nature and amount of support required amount of water that must be handled, speed of sinking, organization of the work, and the equipment employed and labor and other local conditions. The effect of most of these factors upon costs is self

Shaft is a basicponent. The concept of drive shaft design formula is explained in this article with an example shaft design problem.You can see a shaft in almost every machine, which has rotating parts. Typically a shaft has circular cross section. However, shaft with other cross sections find special application. We will discuss the design concept of a drive shaft subjected to

Whenes to design of a mine shaft, there are two options: circular shafts and horizontal shafts Figure 1, Figure 2. Circular shaft is themonly 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. Because of their circular shape, they are easier by the usage. Rectangular shafts, which use timber
and lengths of barrel screw shaft can be used. The length divided by the diameter L/D is a convenient method of describing the geometry of the screw and the length is often quoted as the number of diameters. So for example a 72 mm long screw with a diameter of 18 mm is a 4D screw. A variety of length to diameter L/D ratios can be purchased, typically in the range 24 to 45. Modular machines
