By S.N. Glazer

This publication bargains an in-depth research and interpretation tools acceptable to mine-induced seismicity. it truly is in response to over forty years of expertise in mine and exploration geophysics. one other particular characteristic of this e-book is the entire heritage of the caving strategy as evidenced by means of the recorded seismicity on the South African copper mine Palabora raise 1. previously, the literature has merely offered concept and case stories discussing the translation of effects, and there was no dialogue of the input-data caliber or why a definite interpretation approach was once utilized. This publication fills that gap.

This publication is an interesting learn, written by way of one of many world’s top mine seismologists. It summarises the background and development of mine seismology. It outlines the sensible use of again research of knowledge and the way it may be used every day. The booklet explains how mine seismology can be utilized as a good tracking software for key occasions because the mine progresses in addition to for destiny caving operations.Anthony Allman MAusIMM, CP(Min), RPEQ Antcia Consulting Pty Ltd, Director, Mining Engineer
The content material of the ebook is actually stable and strong and i've without doubt it will be thought of a good contribution for the mining community.Raul Fuentes, Former Director of grasp software in Geomechanics utilized to Mining, Universidad de los Andes, Santiago, Chile
This booklet is lengthy late and is helping to offer a few tricky suggestions in a manner that they are often in actual fact understood by means of non-experts during this zone. Stefan has for my part controlled to take mine seismology from being a black-art right into a great tool to assist make mines a more secure and extra managed setting. Neil Hepworth C. Eng, MIMMM, Geomin Consultorio – Brazil, advisor Mining and Geotechnics
Seismic tracking is a vital instrument in cave administration. the knowledge from tracking permits a couple of key creation elements to be made up our minds together with cave improve premiums, the approximate place of the cave again, perception into the scale of the air hole and permits the monitoring of huge alterations in pressure. those all help in the daily administration of a secure and winning cave. Dr. Glazer’s e-book offers counsel at the program of microseismicity to cave administration via a overview of applicable idea and extra importantly illustrates its use via case histories, rather from the Palabora block cave. The textual content might be a superb addition for all practitioners in cave engineering and operations.Allan Moss, common supervisor – Grasberg Underground Liaison, Copper improvement, Rio Tinto

The seismic velocity model as an interpretation asset

A pace version could have enduring and growing to be interpretive price, past its preliminary construction to optimize the seismic photograph. The three-D pace version is usually outfitted conscientiously with a mixture of geophysical and geologic enter due to the accuracy calls for put on it by means of the necessities of intensity imaging.

To start with this process requires knowing the location of the seismic source as we need to know the distance to which these corrections should by applied. As it will be discussed later the location of the sources are usually not as good as it might be expected. When applying the corrections it is assumed that we know the rock mass properties for example its density or the seismic wave velocities. Although we have an idea about the rock mass properties we do not know their exact values at every point of the rock mass.

However, studies of first motions recorded after big events resulted in reliable fault plane solutions. This gave information about the focal mechanisms of those events; van der Heever (1982), McGarr et al. (1989) and Rorke and Roering (1984). By the beginning of 1990, significant progress was made not only in development of hardware for seismic networks, but also in extracting source parameters from recorded seismograms. But the most important progress was made in the use of seismic source parameters for evaluation of underground hazard.

0. I have had presented the KMMA Klarksdorp Regional Seismic Network procedure of deriving seismic source parameters for several reasons. First of all probably no one remembers or knows how it was done in the past. The second reason is to make it clear that when the digital networks started to operate in mines there was a tendency to consider all what was done to this time as old fashion and useless and that it has to be replaced by the new. To start with the magnitude as such was considered to be a hopeless parameter that soon will be replaced by something better and much more worthy.
