Abstract
The paper presents the results of experimental studies of the physico-mechanical properties of geocomposite used as a covering material for winter blocks of TMF dumps of the Kounrad mine. The changes in the basic strength and deformation characteristics of the material depending on the service life (1 month, 2 years, 3 years) have been studied. The tests were carried out according to GOST standards with the determination of surface density, tensile and tear strength, elongation, yield strength, resistance to aggressive media and repeated freezing and thawing. The results showed that with increasing service life, there is an increase in surface density (from 445 to 604 g/m2) and tensile strength (up to 9.5 kN/m), while reducing elongation. Geocomposite demonstrates high resistance to aggressive environments (up to 96%) and frost resistance, which confirms its durability and suitability for long-term use under conditions of variable climatic loads.
