Potential Utilization of Grounded Bottom Ash for Sustainable Stowing Applications
Authors: , , , , , , ,
Abstract: The present investigation focused on examining the physical, rheological, and mineral aspects of ground bottom ash to enhance comprehension of its utility in the stowing application. Analysis revealed a notable presence of silica in the ash sample, with F-type ash containing alumina and iron oxides while predominant crystalline phases were noticed as quartz and mullite. These characterizations suggest its potential application as stowing material in coal mines, contributing to industry sustainability and mitigating environmental hazards. Experimental results on rheological properties and the impact of concentration on varying pipe diameters indicated a correlation: an increase in pipe diameter led to a slower but evident rise in critical velocity. This data proves invaluable in designing pipeline configurations for stowing bottom ash slurries of differing concentrations and pipe sizes.
