... Abstract There are various methods to determine in situ stress parameters, but each method is having its own advantages and limitations. Among the methods available, the hydraulic fracturing method is the most commonly adopted procedure for in situ stress measurements because of its simplicity...

Special focus is on the determination of the shear parameters by triaxial and direct shear testing. Results of both testing methods vary distinctly due to their sensitivity...

Straight notched disk bending (SNDB) specimens of a limestone were loaded dynamically with the split Hopkinson pressure bar (SHPB) system. Static fracture toughnesses of the limestone were also determined...

... Abstract Pit slope design should be concerned toward economic and technical factors, so output design will be optimum. Determination technical factor must be supported by geotechnical study, so that deep understanding about geotechnical concept is required. In some cases, determination overall...

... Abstract A number of standard methods have been proposed to determine the Mode I fracture toughness of rock. They include those based on short rod specimen, chevron bend specimen and cracked chevon-notched Brazilian disk specimen. The semi-circular bend (SCB) specimen shown in Figure1 has been...

... the character of more continuingly is compared to large scale sample. The discontinuity characteristic which is more at rock mass causes strength of rock would decrease. Determination of Safety Factor (SF) for slope stability analysis by using limit equilibrium method is based upon the ratio of resistance force...

... ABSTRACT The optimum design of a pit requires the determination of the most economic pit limit which normally results in steep slope angles as in this way the excavation of waste is minimized. In general, as the slope angle becomes steeper, the stripping ratio is reduced and the mine economics...
