The longterm effects of underground mining on the growth

The longterm effects of underground mining on the growth

Aug 27, 2020 Underground mining as opposed to opencast often causes largescale subsidence, leading to various types of disturbances to surface vegetation. Adequate quantitative assessment of the longterm effects of underground mining on the growth of different plant communities is important and still lacking. To address these issues, a vegetation growth contract model VGCM was proposed, and six indicators including the growth trend GT, annual growth
