Availability analysis of the main conveyor in the Svea Coal Mine in Norway

引用

International Journal of Mining Science and Technology 2014年第5期24卷 587-591页

作者： Simon Furuly Javad Barabady Abbas barabadi Department of Engineering and Safety University of TromsФTromsФN-9037Norway

Reliability and maintainability of mining industry is more in focus than ever, and the mining systems are becoming more complex and the equipment more expensive to repair or modify. Unplanned failures can result in significant costs, especially when the machinery is hard to repair or spare parts are far away. This paper presents a case study describing a reliability and maintainability analysis of the main conveyor system of the Svea Coal Mine located in Svalbard, Norway. The conveyor system includes several separate conveyors. In this study, the main six conveyors of the whole system were selected for the analysis. The failure and repair data of the conveyors were collected for the whole year of 2010 using maintenance and daily reports. The date was analyzed and the result shows that the availability of six conveyers is 96.44%for one year of operation. However, reliability of these conveyers needs to be improved in order to reduce the number of failures.

Cancer is one of the biggest healthcare concerns in our century,a disease whose treatment has become even more difficult following reports of drug-resistant *** this happens,chemotherapy treatments fail or decrease in efficiency,leading to catastrophic consequences to the *** discovery,along with the fact that drug resistance limits the efficacy of current treatments,has led to a new wave of discovery for new methods of *** use of nanomedicine has been widely studied in current years as a way to effectively fight drug resistance in *** in the area of cancer nanotechnology over the past decades has led to tremendous advancement in the synthesis of tailored nanoparticles with targeting ligands that can successfully attach to chemotherapy-resistant cancer by preferentially accumulating within the tumor region through means of active and passive ***,these approaches can reduce the off-target accumulation of their payload and lead to reduced cytotoxicity and better *** review explores some categories of nanocarriers that have been used in the treatment of drug-resistant cancers,including polymeric,viral,lipid-based,metal-based,carbon-based,and magnetic nanocarriers,opening the door for an exciting field of discovery that holds tremendous promise in the treatment of these tumors.
