Abstract
The urgency of the issue of reclamation of disturbed lands is due to the fact that coal mining by both open and underground methods is inevitably accompanied by exclusion from economic circulation and violation of lands for various purposes, by changing the terrain and forming an industrial landscape. The article contains information on the volumes of disturbance and reclamation of lands in the coal industry In the article the directions of reclamation and applied technologies, domestic developments and foreign experience are considered. It was noted that the priority areas for reclamation of disturbed lands in the coal industry are: agricultural, forestry and sanitary-hygienic. It is noted that the quality of the recultivated areas is not always at the proper level, which creates dif culties in their subsequent use. The main reasons for the low quality of reclamation are the lack of the necessary amount of initial data on the composition and properties of soil and rock mass of the dumps at the development stage of the reclamation projects, the lack of special technical means for performing remediation works at a high level, the lack of a landscape approach to the restoration of disturbed areas. Measures to prevent spontaneous combustion of rock dumps are laid in projects and are not implemented in practice in full, which leads to the occurrence of res. Two new developments in the eld of reclamation are presented: the microbiological method developed by MNIIECO TEK JSC, and the method for restoring the biological productivity of disturbed lands, proposed by the Scienti c Research Institute of Agricultural Problems of Khakassia SB RAAS. Identi ed problem issues in the eld of reclamation and a list of measures to improve the state of protection of land resources. In the article it is shown that in order to improve the state in the sphere of land resources protection in the coal industry, it is necessary to improve the applied mining technologies in order to reduce their land-carrying capacity, to unite overburden operations on the sections with the technical stage of reclamation, to use reproof technologies for formation of waste dumps, to improve quality projects of reclamation and implementation of remediation works.
