How to publish in this journal


The International Journal of Coal Science & Technology is a peer-reviewed Open Access journal focusing on key topics of coal scientific research and mining development. It will serve as an international forum for scientists to present their research findings, and to discuss new developments and challenging issues in the field. The scope of coverage is broad, extending to such topics as: Coal geology, geochemistry, geophysics, mineralogy and petrology – coal basin and coal seam formation and evolution; petrology of coal; organic matter-rich shales, including mineralogy, geochemistry, formation, transport and storage of gases in coal and shales; unconventional energy systems (e.g. oil shales, shale gas, and other carbon-based fuels); ore deposits of materials and rare metals in coal and coal-bearing strata; and groundwater management. Coal mining theory, technology and engineering – coal-measure rocks/ground behavior; mine construction; drift excavation; grouting; support technology; tunnels; mining disaster prevention; green mining; top coal caving; systematic mining technology for super-thick or thin seams; CBM exploration and management Coal processing, utilization and conversion – coal chemistry; beneficiation; liquefaction; gasification; coal water slurry; coal power plant; combustion; coking; by and end products of coal utilization; clean coal technology; low carbon technology; CC(U)S; and IGCC. Coal mining environment and reclamation – Waste management and waste minimization practices; coal mine site closure, decommissioning and reclamation; adverse effects of toxic elements during coal utilization and mining; post-combustion pollution control; waste disposal; and mine water drainage. Other key topics relating to coal science and technology – mine survey; mine health and safety; CO2 mineralization and utilization etc. Join the conversation about this journal

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Total Documents

Evolution of the number of published documents. All types of documents are considered, including citable and non citable documents.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Total Cites 

Evolution of the total number of citations and journal's self-citations received by a journal's published documents during the three previous years.
Journal Self-citation is defined as the number of citation from a journal citing article to articles published by the same journal.

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.

% International Collaboration

International Collaboration accounts for the articles that have been produced by researchers from several countries. The chart shows the ratio of a journal's documents signed by researchers from more than one country; that is including more than one country address.

Citable documents 
Non-citable documents

Not every article in a journal is considered primary research and therefore "citable", this chart shows the ratio of a journal's articles including substantial research (research articles, conference papers and reviews) in three year windows vs. those documents other than research articles, reviews and conference papers.
