Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

open access: yesSafety Science and Technology, Volume 1, Issue 4, December 2026.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Mechanisms of the effects of external fields and polycarboxylic acids on the performance of gangue-based non-cementitious filling slurry

open access: yesCase Studies in Construction Materials
This study focuses on the non-cementitious filling technology for underground coal mines, where the filling slurry is prepared using coal gangue as the aggregate, supplemented by fly ash. Based on the slurry ratio determined in the preliminary tests, the

Underground mining slurry transportation viability

open access: yesInternational Journal of Coal Science & Technology, 2019
Underground mining requires lot of water pumping to surface which increases cost. Because of safety, support, ventilation and environment costs underground mines are closing down gradually all over the world.

Thermophilic anaerobic treatment and biogas generation from wastewater produced in an advanced biorefinery process

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 6, Page 2272-2283, November/December 2026.
Abstract Anaerobic digestion can be an alternative method for treating wastewater from second‐generation biorefineries while simultaneously producing biogas. However, the feasibility of the process and key operational parameters by which wastewater produced in lignocellulosic biorefineries affects reactor performance remain poorly understood.

Kikuyu grass clippings as a bioeconomy feedstock: influence of pyrolysis conditions on biochar properties and its effect on the growth of Swiss chard

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 6, Page 2412-2422, November/December 2026.
Abstract The integration of urban organic waste streams into the bioeconomy is critical for advancing the water–food–energy nexus. Grass clippings, an abundant and underutilized municipal residue, represent a promising feedstock for producing value‐added materials.

Coal-CO[subscript 2] Slurry Feed for Pressurized Gasifiers: Slurry Preparation System Characterization and Economics

open access: yes, 2013
Gasification-based plants with coal-CO[subscript 2] slurry feed are predicted to be more efficient than those with coal-water slurry feed. This is particularly true for high moisture, low rank coal such as lignite.
