Evaluation of brown coal spontaneous combustion and sources genesis prognoses
DOI 10.12914/MSPE-06-04-2014
Abstract: This article presents summarizing information about the solution of partial part of research problem of prognoses of deposited brown coal spontaneous combustion sources genesis as a part of project TA01020351 – program ALFA. We will gradually describe the results of long term measurements carried out on selected brown coal heaps realized from 2011 to 2013. The attention is devoted to characterization of key parameters. These parameters influence the genesis of combustion. The second problem is the comparison of results of thermal imaging with laboratory results of gas and coal samples sampled in situ, with the influence of atmospheric conditions (insolation, aeration, rainfall, atmospheric pressure changes etc.), with influence of coal mass degradation, physical and chemical factors and another failure factors to brown coal spontaneous combustion processes.
Key words: lignite, brown coal, deposit, heap, coal self-ignition, monitoring
