Strata and surface movement induced by mining under open-pit final slope is a huge 8 threat to mine safety. Physical model test is an important method to study mining-induced strata 9 and surface movement laws. Because of rock joints predominantly control rock mass deformation 10 and failure, thus physical model test leaving out of consideration of rock joints is difficult to reflect 11 the inf...

Polymers used in textiles were found to be effective as actuator materials with large deformation. Particularly, the polymers with low dielectric constants used to be considered inactive to electric field were turned out to be efficient actuator materials. They were classified into three types; (1) polymer gels swollen with solvents, (2) plasticized polymers, (3) bulk polymers. From the viewpoi...

The basic properties of conducting electrons in carbon nanotubes are reviewed from a theoretical perspective , and studies performed on persistent currents in toroidal carbon nanotubes and on the local energy gap in deformed nanotubes are reported on. 1 Introduction The Aharonov-Bohm (AB) effect shows the importance of the electromagnetic gauge field in quantum mechanics and the fact that a sin...

Numerical modelling techniques are not new for mining industry and civil engineering projects anymore. These techniques have been widely used for rock engineering problems such as stability analysis and support design of roadways and tunnels, caving and subsidence prediction, and stability analysis of rock slopes. Despite the significant advancement in the computational mechanics and availabili...
