STUDY ON MECHANICAL PROPERTIES OF COAL-BASED SOLID WASTE CEMENTED MATERIALS IN ACID-BASE ENVIRONMENTS

ABSTRACT
Coal-based solid waste cemented materials in underground mines undergo prolonged chemical degradation from mine water. This study investigates the evolution characteristics of apparent morphology and mechanical properties of these materials under acid-base environments through laboratory immersion tests. X-ray diffraction (XRD) analyses quantify variations in relative mineral content, revealing the degradation mechanisms under acid-base environments
KEYWORDS
