In fact, opencast mining is the most directly disturbed way which deteriorate land ecosystem in nature (Guan et al., 2017, Bruno Rocha Martins et al., 2020). Therefore, it is crucial to keep an eye on and conduct study on how opencast mining is affecting the quality of the ecology. The Muli coalfield has a 3.54-billion-ton coal reserve.

Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes. The mineral exposed is completely extracted. Opencast ...
