Abstract

During the period of coal mining in Kuzbass, about 9 billion tons of coal were mined, which is 16% of all in-place reserves of coal in Kuzbass. In 2020, coal production amounted to 220.7 million tons, including 164.4 million tons of open pit mining, which is 74% of the total. The negative side of an increase in the share of open pit coal mining is an increase in the area of disturbed lands, which currently reaches 150 thousand hectares. To restore the biological diversity of dumps, a nature-like technology has been developed for revegetation of dumps, which consists in applying a 15 cm thick loam layer to the dump and introducing a grass seed mixture containing seeds of steppe plants. For six years, a stable, self-perpetuating permanent nature-like community is formed, numbering 30-40 species of steppe plants.

Highlights

During the period of coal mining in Kuzbass, about 9 billion tons of coal were mined, which is 16% of all in-place reserves of coal in Kuzbass
The negative side of the Kuzbass coal industry development and an increase in the share of opencast coal mining is an increase in the area of disturbed lands, in which the general profile of the earth's surface completely changes, biological diversity is completely or partially destroyed [3]
Until the end of the 20th century, the paradigm of the biological stage of reclamation was not aimed at restoring biological diversity, since the formation of plant communities in territories subjected to catastrophic changes obeys the general laws of primary succession [9,10,11,12], which require an extremely long period

Summary

Introduction

During the period of coal mining in Kuzbass, about 9 billion tons of coal were mined, which is 16% of all in-place reserves of coal in Kuzbass. Kuzbass will remain the leading coal-mining region of Russia for a long time due to the presence of large volumes of proven reserves of high-quality coal that meet market requirements, the state of infrastructure, mining conditions and importance in the fuel and energy market of the world [2].
