The present invention aims to provide a sustainable vegetation cover surface that functions as a barrier in mining tailings dams that are out of operation or abandoned to prevent contamination by heavy metals from the air, soil, and surface water bodies. The sustainable vegetation cover surface has a composite substrate based on a mixture of 70-80% mining tailings, 10-15% compost, and 10-15% zeolite that acts as a support medium to provide the necessary elements for the plant species Atriplex canescens (chamizo) and Sporobolus airoides (alkaline grass), which complete the cover surface to adapt, survive, develop, and multiply in an environment contaminated with heavy metals, thereby achieving the remediation of the site. La presente invención provee una superficie de cobertura vegetal sustentable que funciona como barrera en las presas de jales mineros fuera de operación o en condiciones de abandono para evitar la contaminación por metales pesados de aire, suelo y cuerpos de agua superficial. La superficie de cobertura vegetal sustentable cuenta con un sustrato compuesto a base de una mezcla de 70-80% de jal minero, 10-15% de composta y 10-15% de zeolita que actúa como medio de soporte para brindar los elementos necesarios para que las especies vegetales atriplex canescens (chamizo) y sporobolus airoides (zacate alcalino), que completan la superficie de cobertura, se adapten, sobrevivan, se desarrollen y se multipliquen en un medio contaminado con metales pesados, logrando con esto la remediación del sitio.
