Complex technologies such as fully automated and semi-automated equipment and teleoperated machines are being introduced to improve productivity in mines. Consequently, the maintenance and operation of these complex machines is becoming an issue. There is a growing interest in industry in the use and development of technologies to support the collaboration between a local worker and a remote he...

Socio-Technical Systems (STS) theory is rooted in principles that have their origin in action research field projects undertaken by the Tavistock Institute of Human Relations in British coal mines during postwar reconstruction of industry (Trist, 1950). This was a time when mine productivity was failing to increase despite major investments in increased mechanization, while labor turnover and a...

This research entails the extent of up-gradation of Dandot coal, using conventional gravity based sink-float separation techniques, to make it technoeconomically acceptable for the cement industry as a partial substitution of imported coal. In this research, various sizes of run-of-mine coal samples were subjected to specific gravity based sink-float test and resultant fractions were analyzed. ...

For efficient mine planning and economic assessment, knowledge of subsurface structures ahead of mining in 3D and with high resolution is very useful. Tools such as 3D seismology have been adapted from the oil industry and applied to the planning of ultra-deep mines, but these tools lack the resolution to reveal <20 m features that hazard mine workings (Pretorious et al., 1997). Three-dimension...

Nowadays, one of the main tasks of Ukrainian coal industry is increasing labour productivity by means of complex mechanization and automatization of mining operations with usage of modern equipment. The best example is implementation of modern plow complexes on Western Donbas mines, PJSC “DTEK Pavlogradvugillia”. Currently, plowing is one of perspective directions of coal extraction development...

Environmental contaminations resulting from mining operations play an important role in the collapse of ecosystems balance. In order to measure vegetation characteristics and to study soil and plant contamination in rangelands surrounding bauxite mine, a systematic random sampling was done according to physiognomy and homogeneity of vegetation cover. Sampling was performed using a 50-meter tran...

The Infostations wireless data network architecture features discontinuous coverage and ultra-high radio rates for burst transfers of information between base and mobile. It has been shown previously that the infostations architecture can greatly increase the capacity of wireless data systems at the expense of increased delivery delay. In this work we explicitly consider the multiple access iss...

The present work was planned to evaluate the phytoextraction of metal mine tailings, Sarcheshmeh copper mine, SE of Iran, by the endemic plant species Medicago sativa L. (Alfalfa). In this pot experiment, we investigated the effects of seven amendments on the growth of alfalfa and uptaking metals from the mine tailings and stream sediment of tailing dam surface. The mean metal concentrations in...

Using data on work accidents and annual mining statistics, the paper studies work-related accidents in the Spanish energetic mining sector in 1999-2008. The following 3 parameters are considered: age, experience and size of the mine (in number of workers) where the accident took place. The main objective of this paper is to show the relationship between different accident indicators: risk index...

One of the most important challenges facing organizations is the increasing levels of job burnout among their employees. In the meantime, it poses the question as what the relationship between this factor and job satisfaction is. The aim of this study was to investigate the relationship between burnout and job satisfaction to provide an appropriate model. The population of this study consisted ...
