fluctuation of exchange rate and its deviation from equilibrium path are one of the most important macroeconomic variables that is affected by different side of economical sectors. whereas, the exchange rate fluctuation and its deviation from equilibrium path haven’t the same and similar effects on all of the economical sectors, and considering eminent important of industrial development on the...

In this study, a limit equilibrium method has been developed that satisfies all conditions of equilibrium and assumes circular slip surfaces. All force and moment equilibrium equations are employed without using simplification assumptions. A non-linear optimization technique is used to solve the system of equations with the corresponding constraints. The proposed method is capable to determine ...

Drawing on the theories of limit equilibrium and finite-element strength reduction, this paper explores instability modes stability change laws slope in zones E, W, S Jiajika spodumene mine, through rock mechanics tests, field survey, numerical simulation. The results show that sliding mode is circular arc or + plane sliding. Overall, final open-pit mine generally stable under current design, s...
