Shaft Design, Construction Consulting Engineering

Shaft Construction. Generally, shafts are constructed from the ground surface down, using conventional shaft sinking methods. However, in rock tunnelling projects, shafts not used for primary construction access can be constructed using raise boring. In raise boring, a mall pilot hole is drilled from the ground surface to tunnel depth.

Structural Design of Reinforced Concrete Deep Shafts Inserted

Abstract: In the design of deep shafts inserted into fractured rock masses it is important to know the behavior and distribution of the vertical loads between the concrete structure and the rock mass. With the purpose to know this load distribution, this work develops an analytic model for the load distribution

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. Control of ground conditions is a key factor in the design and sinking of shafts

Design Aspects of Concrete Lined Vertical Shafts for Hydropower

Vertical shafts have a higher ground coverage compared to surface parallel inclined shafts. The increased rock mass cover and therefore higher in-situ stress magnitudes (e.g. decreasing risk for hydro-fracturing) may allow unlined solutions instead of cost intensive steel lining (providing that water losses are economically acceptable).
