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...

Abstract This work presents attempts to synthesize silver-doped copper nitride nanostructures using chemical solution methods. Copper(II) nitrate and silver(I) were used as precursors the oleylamine a reducing capping agent. Homogeneous Cu 3 N/Ag with diameter of ~ 20 nm obtained in one-pot synthesis by addition copper(II) salt precursor already-synthesized silver nanoparticles (Ag NPs). Synthe...
