Identification of the life of mining enterprises in context of reclamation processes

The article proposes a methodological approach to determining the full life of mining enterprises, considering the mining and biological processes of land reclamation. It also describes the working area of the strip-pit with elements of stripping, mining and reclamation operations, which predetermine its contour and establish the main parameters of the working area, and the technology of opencast mining in the development of flat deposits. The paper also describes the time (the number, sequence, and duration of the mining and biological reclamation processes at the enterprise facilities) when it is necessary to achieve certain economic indicators based on calculations of mining operations efficiency by year
