Abstract

This study provides characterization of Menouna coal from the Abadla Basin, Algeria, using a multidisciplinary approach that integrates geological mapping, lithological logging, proximate and ultimate analyses, and calorific measurements of Higher and Lower Heating Value (HHV/LHV). Analytical techniques, conducted in accordance with international standards (ASTM and ISO), reveal key properties, including a moisture content of 7.2 %, ash content of 6.6 %, fixed carbon content of 46.4 % and a high organic carbon content of 75.6 %. The coal was classified as medium-grade bituminous with a low sulfur content (1.015 %), making it suitable for environmentally friendly applications. The HHV analysis yielded an average value of 34.00 MJ/kg, while the LHV analysis showed an average value of 32.78 MJ/kg, confirming the coal's significant energy potential. These findings highlight Menouna coal's suitability for power generation, cement production, and metallurgical processes, while aligning with global efforts to reduce emissions and promote sustainable energy use. The study underscores the strategic importance of Menouna mine in Algeria's energy landscape and provides essential data for future resource exploration and management.

Abadla盆地Menouna煤的岩性填图、元素和热特征及其应用前景

本研究采用多学科方法对阿尔及利亚Abadla盆地的Menouna煤进行了表征，该方法将地质测绘、岩性测井、近似和最终分析以及高热值和低热值（HHV/LHV）的热量测量结合起来。根据国际标准（ASTM和ISO）进行的分析技术揭示了其关键特性，包括水分含量为7.2%，灰分含量为6.6%，固定碳含量为46.4%，有机碳含量为75.6%。该煤被归类为中等烟煤，含硫量低（1.015%），适合环保应用。HHV分析的平均值为34.00 MJ/kg， LHV分析的平均值为32.78 MJ/kg，证实了煤具有显著的能源潜力。这些发现强调了Menouna煤在发电、水泥生产和冶金过程中的适用性，同时与全球减少排放和促进可持续能源使用的努力保持一致。该研究强调了Menouna矿在阿尔及利亚能源格局中的战略重要性，并为今后的资源勘探和管理提供了必要的数据。

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
