  • Heavy media coal hydro-transport in Malinau, Indonesia: a process study

    In Indonesia, coal transportation has traditionally been handled by trucks and by other mechanical means. With the expansion plan of coal production and increasing truck costs, Kayan Putra Utama Coal believes that alternative modes of transportation must be considered. For long distance transport of export size coal, one of the most viable options is to use coal slurry pipeline. This paper ...

  • Fast and reliable safety surveillance in coal silos – Case Study

    CO Monitoring in Coal Silos Coal Silos are widely used nearby mining facilities or as intermediate storage containers at steel or cement plants. A major threat in running this facilities is the random occurance of partial self-ignition of the coal. This leads to elevated CO concentrations inside the headspace of the silo. This self-ignition is hardly to predict, since its occurance ...

  • Lead distribution in Permo-Carboniferous coal from the North China Plate, China

    The content and distribution of the lead in coal, gangue and the sulfur ball and the pyritic gangue of the Permo-Carboniferous in the North China Plate have been systematically studied (nearly 300 samples) in this paper. The Permo-Carboniferous coals in the North China Plate account for nearly 44.45 of total Chinese coal resources, and most of the steam coals in China come from the ...

  • Downsizing through technology management and outsourcing: a case study of a captive coal-mining organisation in India under globalisation

    The organisation under discussion is a part of a Steel Company and consists of a group of captive underground coal mines required to produce coking coal, wash it in the coal washeries (benefitiation plants) and send the good quality clean coal to the steel plant for steel-making. The emergence of liberalisation in India has affected Indian industries and compelled them to think of ways to become ...
