Blastability evaluation for rock mass fragmentation in Iran central iron ore mines

Iron Ore Rock Recognition Trials

The fatigue in workers of Iran Central Iron Ore Company in Yazd.

AIMS To evaluate fatigue, sub-dimensions, and job satisfaction among workers of Iran Central Iron Ore Co., and obtain the relationship between them. MATERIALS AND METHODS In a cross-sectional study, fatigue and the dimensionality were measured using Iranian version of Piper Fatigue Scale questionnaire (PFS). Job satisfaction was estimated with the job satisfaction scale (JSS) as well. RESUL...

Evaluation of Social Performance and Related Factors in Iranian Central Iron Ore company workers

Introduction: Psychological and social health is the main problems of workers population, which can increase productivity at work and physical and mental health and provide or decline in these aspects. Materials and Methods: this study was descriptive and crosses - sectional and has been performed on 388 Iranian central iron ore company workers. The tool of study was standard GHQ-28 question ...

evaluation of rock mass deformability

One of the most important effective parameters in design of engineering structures is deformability of rock mass. Benchmark of rock mass deformability is the deformation modulus that directly or indirectly obtained. Since the determination of rock mass deformation modulus indirect method by in-situ tests is time-consuming, costly and difficult from executive operations aspect, so it’s correctly...

Rock mass structural data analysis using image processing techniques (Case study: Choghart iron ore mine northern slopes)

Presence of joints and fractures in rocks strongly influences the behavior of the rock mass by dividing the media into smaller units. These structures intensify the potential instability besides the development of sliding and rotational movements. The assumption of discontinuum media changes the whole analysis conditions in relation to the continuum analysis. Acquisition of geometrical and stru...
