Recent advances in mobile and wireless technology have made possible new types of information systems supporting key activities in transport organizations. By including mobile actors and equipment, such technology is a key enabler for realizing the vision of enterprise system support in this context. This paper focuses on a particular type of transport organization, that of road haulage firms. ...

This article examines the importance of path dependence effects in impeding the diffusion of high throughput mechanized mining systems in the British coal industry. It demonstrates that the industry had become ‘locked in’ to low throughput underground haulage technology, on account of institutional interrelatedness between Britain’s traditional practice of extensive in-seam mining and its uniqu...

The empirical da...

The past decade shows record increases in global demand for minerals and metals with an accompanying significant decline in skilled personnel. Mining companies today are examining new technologies to maximize production, reduce costs, and create safer work conditions to deal with this shortfall. Automation of an open-pit mine haulage system is receiving attention as a beneficial option since it...

Researchers at the National Institute for Occupational Safety and Health (NIOSH), Spokane Research Laboratory, are investigating technology and methods to monitor the blind areas around large haulage equipment used in surface mines. On average, six fatalities a year can be attributed to equipment colliding with other vehicles or pedestrian workers, or backing over the edge of a dump point. Seve...

Tele-operated Load Haul Dump (LHDs) machines are becoming a common tramming solution throughout many mines at INCO Limited in Copper Cliff, Ontario, Canada. To reach maximum productivity from multiple teleoperated LHDs, the system must achive a proper balance of LHD speed in the haulage network and haulage layout geometry. A study was inititated to determine if multiple LHDs, tramming in second...

The appropriate operating of mining machines is affected by both the executive and environmental factors. Considering the effects and the related risks lead to a better understanding of the failures of such machines. This leads to a proper prediction of the reliability parameters of such machines. In this research work, the reliability and maintainability analysis of the loading and haulage mac...

This paper presents a simulation framework incorporating traffic simulator with classical discrete event simulation model of internal transport systems. The objective behind this integration is to provide a simulation model in which traffic is captured in the internal haulage networks. For this purpose, the highly detailed microscopic traffic modelling approach is adopted. The developed simulat...

collection of municipal solid waste (msw) accounts for a significant proportion of most municipal budgets, and has drawn some degree of researchers‟ interest. this study was conducted in ota, southwest nigeria, to explore the use of visual basic program as an innovative tool to select the most economic haulage system among three systems found in literature (conventional-, modified- and stationa...

Hexavalent chromium wastes need to be chemically reduced to trivalent chrome in the shop’s treatment plant. This necessitates the use of expensive chemicals such as sulfur dioxide, sodium metabisulfite or sodium borohydride. Also considerable hazardous sludge is generated during the neutralization step of the treatment process due to the high chromium concentration of the plating solutions. Haz...
