Abstract

Komur yapisi geregi oksijeni adsorplamaya ve oksidasyona yatkindir. Komurun kendiliginden yanmasi oldukca karmasik ve hala tam olarak aciklanamamis bir mekanizmaya sahipse de gunumuzde en yaygin kabul goren kuram komur oksijen birlesigi kuramidir. Bu kurama gore komurun kendiliginden yanmasi yavas oksidasyon, hizlanan oksidasyon ve hizli oksidasyon asamalarindan olusmaktadir. Surec icerisinde oksijenin fiziksel ve kimyasal adsorpsiyonu ile serbest radikallerin reaksiyonlari sirasiyla dominant etkiye sahiptirler. Komurun ve/veya komur atiklarinin bulundugu her yerde kendiliginden yanma herhangi bir dis mudahale olmaksizin meydana gelebilmektedir. Kendiliginden yanmayi etkileyen parametreler acisindansa genellemeler sakincali olup, bazi yerlesmis bilgilerin hatali olabilecegi gunumuzde ortaya konmustur. Ornegin; komurun kendiliginden yanmasi sanildigi uzere sadece ranki dusuk komurlerde gerceklesmez, yuksek pirit icerikli komurlerin kendiliginden yanma egilimi dusuk cikabilir ya da egilimi dusuk olan ve risk teskil etmedigi dusunulen komurlerde yillar sonra kendiliginden yanma gorulebilmektedir. Bu sebeple komurlerin kendiliginden yanma egilimleri belirlenmeli, uretim, stoklama ve nakliye gibi tum asamalar detayli sekilde planlanmali ve surekli takip ile kontrol yapilarak acil mudahale planlari da hazirlanmalidir.

期刊介绍: Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
