What are the negative effects of open cast mining on the environment?

Answers. (i) Large scale blasting of rocks leads to instability of the basement rocks. Water collects in the hallows left by open cast mines creating ponds which becomes habitats for disease causing organisms. (ii) The land is left with gaping quarries, which ugly, interfere with the natural beauty of the landscape.

Open Pit Mining - an overview | ScienceDirect Topics

An open pit mine is typically excavated with a series of benches to reach greater depths. Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and loaded onto dump trucks, which then transport the ore to a milling facility.
