mining engineering: Shaft Design
For a production shaft, design starts with determining the cross section or plan view of the shaft. The production shaft is designed to the minimum dimensions required to contain and guide the shaft conveyances, as well as provide space to place and access the utility lines.

A METHODOLOGY FOR LINING DESIGN OF CIRCULAR MINE SHAFTS IN DIFFERENT ROCK MASSES submitted by ERDOöAN GÜLER in partial fulfillment of the requirements for the degree of Master of Science in Mining Engineering Department, Middle East Technical University by, Prof. Dr. Canan Özgen Dean, Graduate School of Natural and Applied Sciences
DESIGN OF MINE SHAFT ELEVATOR - mech-ing.com
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 4.5 meters, circular shafts are the best choice.

Shaft design criteria | SpringerLink
1-7-1984 · 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. Factors considered, apart from geotechnical criteria include constraints imposed by surface structures, mineral ...
A methodology for lining design of circular mine …
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 non-hydrostatic stress state in an attempt to predict the pressures developing around mine shafts.

Shaft mining - Wikipedia
Shaft mining or shaft sinking is excavating a vertical or near-vertical 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 projects.When the top of the excavation is the ground surface, it is referred to as a shaft; when the top ...
Geotechnical design considerations for mine shafts …
The design, development and operation of a shaft system is a critically important element in mining, and needs specialised technical input. Experience has shown that the consequences of damage to shaft systems caused by geotechnical factors are serious and costly.
