Lecture 7: Stress Analysis around Underground Openings
Underground Openings 2 of 40 Erik Eberhardt – UBC Geological Engineering EOSC 433 (2007) Flin Flon Mining Belt Since 1927, Hudson Bay Mining & Smelting ... vein is parallel to the intermediate stress, and the major principal stress is horizontal with a magnitude of 37.0 MPa.
(PDF) Stability analysis of underground mining …
Stability analysis of underground mining openings with complex geometry. ... the potential interaction between adjacent galleries is an important issue to the layout design of the repository.
Magnetic generator – Infinity SAV
Due to the special material of the coil’s core (transformer steel), capacity for a set value of the potential difference between turns has been significantly enhanced. The Magnetic Generator operates and is able to generate power due to interaction of permanent magnets with bifilar coils and an emerging electromagnetic force between them.
STRESS DISTRIBUTION AROUND THE TUNNEL: INFLUENCE OF …
of any underground excavations are the shape and size of opening, in-situ state of stress, induced stress field and related deformations when the openings are made. To ensure safe and economical construction of underground sections one should know the distribution of stresses around the tunnel.
Interaction Between Parallel Underground Openings
interaction phenomenon occurring between closely located and unsupported parallel underground openings are investigated. „Firstly, the approaches commonly employed for siting of parallel tunnels or underground galleries are summarized. Then, secondly, the mathematical or closed-form solutions available for the stresses around parallel tunnels are reviewed. Thirdly, important features of a …
Stability analysis of underground mining openings …
Stability of mining openings requires consideration of a number of factors, such as: geological structure, the geometry of the underground mining workings, mechanical properties of the rock mass, changes in stress caused by the influence of neighbouring workings.

INTERACTION BETWEEN TUNNEL OPENINGS DUE …
INTERACTION BETWEEN TUNNEL OPENINGS DUE TO VIBRATION EFFECTS. A major field of interaction effects in the case of openings used as underground railway tunnels covers the dynamic effects due to vibration caused by moving trains in tunnels. The dynamic loads may be caused by high speeds or high loads but low speeds.

Mining - Underground mining | Britannica
Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on …
