The Working Group
"Estimating Primary State of Stress in Rock Mass using Acoustic Emission Technique"

Co-ordinator: Masahiro Seto (Japan)

The Workong Group made the draft on "Suggested Method for in-situ Rock Stress Estimation from a Rock Core using Acoustic Emission Technique".
This draft had been approved by the ISRM Commission on Application of Geophysics to Rock Engineering, and also had been approved by ISRM Vice-President for Asia before ISRM 2003 Council Meeting on 7th September 2003. Therefore, this suggested method will be published as one of the ISRM Suggested Methods.

The contents of the Suggested Method is as follows:
1. Introduction
2. Scope
3. Terminology
4. Apparatus
5. Procedure
6. Calculation and interpretation of results
7. Reporting of results
