Paper presented at the ISRM International Symposium on In-Situ Rock Stress, August 25–27, 2010
Paper Number: ISRM-ISRS-2010-108
... ABSTRACT: p value in Omori's law and the b value in G-R relation are probably the most broadly accepted statistics in seismicity study. In this paper, we focused on the p and b values of two great earthquake sequences occurred in China, the 1999 Chi-Chi Mw7.6 earthquake...

Paper Number: ISRM-ISRS-2010-139
... successfully many times by anomalies of crustal stress, we found and proved that the direction of anomalous principal stress is pointed at or mined to epicenters, the stations with higher anomalous principal stress were near the epicenters, and the duration time of long-termanomaly was linearly related...

... of Daqing oilfield, it proved the relation of rock body stress and seepage rate. According to the numerical simulation for the in-situ rock stress field changes of oilfield before and after slotting, the mechanism of abrasive jet cutting in oilfield to increasing production is found. Slotted through wells...

Paper Number: ISRM-ISRS-2010-030
... until failure. Experimental study on rock damage process under cycling load based on acoustic emission technique was carried out. Mathematical relation between rock damage and AE counts based on damage theory and load/unload response ratio theory was established to study rock damage process and Kaiser...

Paper Number: ISRM-ISRS-2010-060
... from 6 coal mines Kailuan mining area, China. According the analysis of the measurement data, the characteristic of in-situ stress field is obtained. At last the relation between in situ stress and geological structure was discussed. The result provided a more precise and reliable stress environment...

Paper Number: ISRM-ISRS-2010-119
... in faulted areas can be calculated and then used to assess the potential of regional seismic hazard. The second goal of this study is application of a constitutive relation which represents the governing equation of the failure process and specifies the dependence between stress, fault slip, slip rate...

... of the in-situ stress regime using hydrofrac technique provided the following relations. Vertical stress, Major horizontal stress, Minor horizontal stress, The caverns for the project of M/S SALPG are cited at a depth in between 162 m to 186 m. The above mea- surements are carried out up to the depth of 150 m...
