Keywords: Hoist, small scale mine, design, cost, rope, winder, electric motor 1. Introduction With mining increasingly becoming a main contributor to economy, it has become necessary to improve mining so as to harvest greater benefits. In many small scale mines, productivity hence economic growth is being hampered by * Corresponding author.

The Design Center of the Company carries out comprehensive planning of shaft sinking, horizontal and inclined working, and other mining facilities in various mining and geological conditions, by special methods as well, and of the entire top shaft works.
Summary. Criteria for shaft design are described and methods of design developed. Among aspects covered in detail are: selection of shaft locations; shaft collar design and determination of collar dimensions; shaft lining design and estimation of side pressures; shaft insets and sump design.
In this page we are presenting online fan shaft power based on input parameter like air flow, total pressure and fan efficiency this is fan shaft power and no motor efficiency and other factor consider, in different industry actual power consumption of fan may change due to other factor like venturi or diffuser etc. so this is just a basic calculation based on airflow and total pressure you ...
of the Mining Journal,, and many other members of the mining community, the Hard Rock Miner''s Handbook has been distributed to over 113 countries worldwide. Web hits and downloads continue as students and professors, miners, engineers, and mining executives embrace the Handbook as an invaluable source of practical
Preliminary shaft diameter design. [1] In this paragraph you can make a preliminary design of the shaft diameter based on the transmitted power, speed and loading regime. Use this value then as a default (orientation) value when executing a design of the real shape of the shaft. Calculation units.
that process is called "deep mining". When it comes to design of a mine shaft, there are two options: circular shafts and horizontal shafts (Figure 1, Figure 2). Circular shaft is the most commonly used one. If the shaft should be deep and shaft diameter is supposed to be more than meters, circular shafts are the best choice.

Shaft mining or shaft sinking is excavating a vertical or nearvertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining the top of the excavation is the ground surface, it is referred to as a shaft; when the top ...
Shaft Diameter Calculations Design Engineering Discussion Forum . Design and Engineering Forum. Home ... Shaft Diameter Calculations: ... For example I know the torque vaule, the type of loading (repeated torsion), the length of the shaft with the maximum amount of Angle of twist. T=50,000 Loading = 4 Shaft length = 20 foot
Pillar design considerations. ... The common design methods include tributary area, empirical calculations and modelling. Shaft Pillars. ... In order to overcome these problems, the pillar area must be mined out which can be done during mining or prior to sinking the shaft.
the shaft of the idler is stationary and does not rotate. Therefore, it is not subject to the same fatigue analysis as a rotating pulley shaft. The other difference between pulleys and idlers is that the idler shaft is designed once and the same design is used repeatedly. However, pulley shafts will often be a unique design that is seldom ...

Shaft is a basic mechanical component. The concept of drive shaft design formula is explained in this article with an example shaft design 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 ...
USA, the design methodology for shaft lining is based on the mining traditions and experience of those regions. Design methods for the shaft lining and shaft stations can be divided into three main groups, namely: analytical, numerical and empirical ones. Analytical methods are .
In this study, a new methodology for lining design of circular mine shafts in different rock masses is developed. A parametric study is carried out using the finite element numerical modelling of 2D shaft sections in a Hoek–Brown Medium in a nonhydrostatic stress state in an attempt to predict the pressures developing around mine shafts.
