Stability, instability and design of pillar workings
TLDR
In this article, the stability of pillar workings is discussed by generalizing the simple mechanism of the laboratory test to the mining situation, and it is proved that the workings will remain stable, regardless of the magnitude of the convergence experienced by the pillars, if the minimum slope of the load-convergence relations is greater than the smallest eigenvalue of K taken with a negative sign.About:

Dynamic behaviour of mining-induced fault slip
Atsushi Sainoki,Hani S. Mitri +1 more
TL;DR: In this paper, the authors conducted a dynamic numerical analysis of a fault parallel to a tabular ore deposit and showed that the maximum dynamic shear displacement increment induced by stope extraction is significantly affected by the friction angle of the fault, as well as mining depth and position of fault with respect to the orebody.

Rockbursts and the instability of rock masses
TL;DR: The Schlumberger Lecture Award for 1994 as mentioned in this paper was a great honour and privilege to receive this prestigious award, and I am very grateful to the Selection Panel and its Chairman, Professor John Hudson, for selecting me as the lecturer.
BookDOI
Rock Mechanics for underground mining: Third edition
B. H G Brady,E. T. Brown +1 more
TL;DR: Although Rock Mechanics addresses many of the rock mechanics issues which arise in underground mining engineering, it is not a text exclusively for mining applications as discussed by the authors, and it consists of five categories of topics on the science and practice of rock engineering: basic engineering principles relevant to rock mechanics; mechanical properties of rock and rock masses; design of underground excavations in various rock mass conditions; mining methods and their implementation; and guidelines on rock mechanics practice.
Journal ArticleDOI
Numerical simulation of rock burst processes treated as problems of dynamic instability
Aleksander Zubelewicz,Zenon Mróz +1 more
TL;DR: In this paper, after solving the initial static problem, the mode and onset of dynamic failure are studied by superposition of dynamic disturbances, which may be handled in a relatively simple manner.
Journal ArticleDOI
The theory of post-failure deformations and the problem of stability in rock mechanics
I.M. Petukhov,A.M. Linkov +1 more
TL;DR: In this paper, the authors consider the effect of post-failure characteristics on the phenomenon of destruction, give complete systems of equations for the theory of post failure deformations, and formulate criteria of stability and definitions adequate for the physical processes.

A study of the strength of coal pillars
A.H. Salamon,M.D.G. Munro +1 more
TL;DR: In this paper, the strength of coal pillars in South African collieries is derived based on data obtained from a survey of actual mining dimensions, which include information concerning both stable and collapsed areas of mining.
Journal ArticleDOI
The failure of rock
TL;DR: In this paper, an analysis of the energy changes associated with the extension of Griffith cracks in tension and compression is made, which shows that the non-elastic behaviour can be described by a curved Griffith locus in the strain-stress plane.
