Rock strength experiments and failure criteria,he nature of the rock in which important quantities, often stress and strain, are determined (Jaeger and Cook 1979). Before laboratory tests, rock sample preparation and physical analysis are needed. The ISRM standards gave the suggested methods for both core preparation and testing (Brown 1981, Kov

Double porosity poroelasticity and its finite element solution,he exploration and production of hydrocarbons now occur in more difficult geological settings; such as in naturally fractured media, in overpressured shale formations, in rubble zones of sub-salt formations, and at great depths. In fractured porous formations, borehole instability has been of major

Strata failure and mining under surface and ground water,r example, there are about 125 rivers flowing through China‘s coal fields, and more than 200 coal mines are confronted with the problems of mining under rivers. For groundwater, there are three main possible water disasters affected safety operations of coal mines (Zhang et al. 1997, Peng and Meng 2

Stability of underground excavations, a formation subject to biaxial stress is examined, as shown in Fig. 11.1. The biaxial stresses in the far-field of the excavation are assume ed as_σ. and .σ.. The analytical solutions for stress and displacement distributions around the circular opening can be expressed as follows (Brady and Brown
