Open-Pit Mining And Its Impacts On The Environment

The open-pit mining method generates enormous environmental impacts in the territory on which it is developed; some of these are: Damage to the earth's surface destroys and changes the shape of the earth's crust, forming large amounts of waste material, altering the local morphology. It pollutes the air; during this activity, large amounts ...

Untangling the complex web of environmental, social, and …

Ranjan et al. (2018) and Yakovlev et al. (2019) stated 600 m as a deep open-pit mine, while Rimmelin and Vallejos (2020) defines a deep open-pit mine to be 500 m depth. Bazaluk et al. (2023) considers a deep open-pit mine with depths between 500 and 705 m. Characterization of a large-scale mine is also determined by various factors, …

FACT CHECK: Open-pit mining ban stays in South Cotabato

The lifting of the open-pit mining ban, imposed since 2010, is a hot social issue in South Cotabato, with the local Catholic Church leading the efforts for the prohibition to stay on concerns over the environment, human health and food security. ... in effect misleading the public.
