The study entitled “Technology of Mine Closure Plan in the Non-metallic Economic Administrative Unit (EAU) named “Los Conjuntos I“, is addressed to realize a standard mine closure of both zones: “Sara” and “Ágata I”, which are included in the EAU; in this sense the mining owner put into practice a highly structured process of rehabilitating action at all stages of the life cycle of the mine, according to technical standards applicable and recognized for both domestic and international ways. For this purpose, the closing activities are the following: dismantling of mine workings and other installations, demolition of buildings, recovery and disposal of solid waste, as well as donation to the communities on the direct influence area of the facilities, access roads and camps. Other activities of closure are the following: stabilize the shape of the land by means of rehabilitation of some habitats and restoring the landscape of the area through of the revegetation, continuously monitoring of the air quality, noise and water; as well as upgrade the capacity of physiographic, edaphic studies, land use, physiographic, geological, climatological, meteorological, hydrological, hydrogeological and complementary biological studies. Additionally, for the final closure of mine workings, geomechanical studies will be undertaken to determine rates of physical stability of the rocks , which results will be taken into account in order to design of the covers that will finally close the mine drifts and raises. In the other hand, while the phases of progressive closure and final closure are performed, it will be developed a consulting plan, from which social programs will be implemented in order to research the socio-economic trends of the direct influence area community, using for that methods of training with appropriate socio-pedagogical procedures. For the same, the proposed activities of post-closure detail schedules of multidisciplinary maintenance and monitoring will mitigate potential environmental impacts that may be caused by some weather agents. This study will also include the estimate of the schedule, budget and financial guarantee of the Mine Closure Plan, for the next 5 years, recorded from the date of project approval by the competent authority. The total value of the estimated Closure Plan is US$ 356 563, distributed in the following manner: a) Progressive Closure: US$ 295 442; b) Final Closure: US$ 38 364; and c) Post Closure: US$ 22 757. The activities of closure in the two mentioned mining units are being implemented up to date, without any delay nor problem, given that there is no generation of acid waters and the emission of dust is practically null and void.
