Mining Leachates Effect on the Hydraulic Performance of Geosynthetic Clay Liners under Different Temperatures

Geosynthetic clay liners (GCLs) are often used as anti-seepage systems in landfills and at the bottom of tailing ponds. The performance GCL will change under different temperatures. In this study, bentonite was mixed with test solutions temperatures to measure basic indexes components analyze permeability. composition micro-structure were analyzed by X-ray diffraction, fluorescence spectrum, SEM, rule permeability property mine leachates understood combining macro-measured parameters microscopic analysis results. research results indicate that fluid loss two bentonites increased increasing temperature due inhibition ion exchange between mixture temperature. swelling index high showed increase pore size attributed temperature, uneven distribution resulted intrinsic study would provide reference for application mining.
