Utilization of Coal Mine Waste in Vegetation

Abstract

The overburden (OB) removed to access the coal deposits is being dumped in the form of OB dumps. Once it reaches the permissible height, the dumps will be vegetated in order to increase the green cover of the area as well as to stabilize the dumps. In this regard, a systematic research study is taken up by adding different additives to coal mine waste, such as fly ash and specific species are planted to assess the growth of different plants. It was found that plants have grown to more height in sewage waste mixed with OB up to 50%. © 2022 Ram Chandar Karra, Gayana B.C and Shubhananda Rao P.
