slope stability is one of the major and determiner parameters in the economy and safety of open pit mines. failure and consequently rupture of the slope caused no compensable economic and humanity losses. so, probability assessment of the further failure for presentation of damages and additional costs is of prime importance. in this research, stability analysis and probability assessment of th...

Today, most research institutes dealing with landmine detection as a topic and even within many mine action communities there is a stereotype landmine image, where the only challenge is considered to be the detection of the small lowor nonmetallic anti-personnel blast mine. Indeed, this plastic cased pressure operated mine is difficult to detect. However, to the well protected deminer adhering ...

Area Denial concepts, as applied to the next generation of scatterable mines (NGSM), are oriented to the philosophy of greatly reducing the cost and logistics burden of the current family of scatterable mines (FASCAM) while maintaining or improving their effectiveness. By extending the sensing radius of the mines and employing some level of warhead mobility, each mine can protect a larger surro...

Application of fine, inert ‘rock dust’ (RD) to the surfaces in underground coal mines is a common method for mitigating dust explosion hazards. However, due its size, RD has potential contribute respirable mine (RCMD) concentration. Though component RCMD does not appear pose sort health hazards associated with other components such as crystalline silica, understanding relative abundance may be ...
