The development of the extractive industry leads to the increase in the number of quarries on the territory of the Crimean peninsula and, as a consequence, to the increase of the area occupied by the disturbed lands requiring recultivation. The reclamation of such land plots on the basis of creating the necessary conditions for the development of regenerative successions of zonal vegetation on them and ultimately the formation of soils is much cheaper for land users. Therefore, studies of the rates of soil formation, including using the methods of mathematical modeling of the processes of formation of the humus horizon of the soil over time, have become relevant. Calculation of the economic efficiency of reclamation of the disturbed lands has been carried out for the Alexandrovskoye saw- limestone field in the Chernomorsky region of the Republic of Crimea. The assessment has been carried out within the framework of two models: mining engineering with further self-overgrowing of the reclaimed land plots under pastures and integrational, including both mining engineering and biological stages with possible carrying out a number of agrotechnical works on further improvement of pastures, based on the calculation of the cost-effectiveness indicator. This indicator is based on the selection of the best options for remediation work at the minimum value of the integral operational and investment costs and takes into account the effect of the time factor. The calculation results have shown that, in terms of cost-effectiveness, it is more rational to use the mining engineering model with further self-overgrowing of the sites to be reclaimed when it comes to the reclaiming of the disturbed lands of the Alexandrovskoye quarry.
