Abstract

The exploitation of open pit mines in grassland brought many environmental problems. In this study, two sizeable open-pit lignite mines in Inner Mongolia grassland were selected for study. We investigated the vegetation and soil status of grasslands surrounding the coal mines. By comparing grasslands covered with coal dust (GD) to the adjacent normal grasslands (CK), we found that the vegetation coverage, grass yield, soil organic carbon, and soil nitrogen content of GD grasslands were lower than those that in the CK grasslands. Based on the Chinese grassland degradation standards, we made an evaluation and found that there was moderate-severe degradation of grassland around the mines after seven years of mining. We can conclude that the exploitation of lignite mines caused the degradation of surrounding grasslands, and we should pay attention to the controlling of pollutants emission and protecting the natural grassland.
