Mechanism of Coal Spontaneous Combustion in Goaf and Mine Fire Prevention

Dear Colleagues,

Coal fires are a major disaster that threatens the safety of mine production, with the vast majority of fires caused by coal spontaneous combustion, which often occurs in enclosed spaces such as gobs, coal pillars and structural belts. In terms of the occurrence and development laws of coal fires, existing research mainly includes: 1 The self-heating oxidation characteristics of coal; 2. Numerical simulation calculation/similar simulation experiment based on commercial software; 3. Early prediction and monitoring of coal fires; 4. Application of fire prevention and extinguishing technology/materials. However, many important details, such as the combustion characteristics of coal at high temperatures and the fire-extinguishing efficiency of composite materials, to name a few, still need further attention.

This Special Issue aims to to gather recent studies on the disaster mechanism and fire extinguishing technology of coal fires. It aims to combine experiments and on-site observations with numerical simulations to reveal the dynamic evolution process of underground fires. Research areas may include (but are not limited to) the following:

1. Low-temperature oxidation characteristics of coal;
2. Disaster mechanism of mine fires/spontaneous combustion;
3. Theoretical modeling method and numerical simulation;
4. Fire source location detection (gob, coal pillar, roadway, etc.);
5. Development of fire extinguishing materials and equipments;
6. Early warning and control technology for underground coal fires.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fire is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
