opencast opencast mining environmental impacts

Opencast Mining an overview ScienceDirect Topics

18.3 Impacts of mining activities on environment and climate change. Opencast mining operations involve the removal of huge quantities of overburden, dumping, and backfilling of the excavated area. These overburden deposits of waste material containing low-grade ores are represented as mine spoil dumps.

Environmental impacts of deep opencast limestone mines

Deep opencast mines for limestone of Upper Cretaceous age in the northernmost state of Germany, Schleswig-Holstein, greatly impact the local environment. In three pits with depths of nearly 100 m, mine pumping affects deeper aquifers and sometimes shallow ones as well. The total amount of mine water pumped ranges up to 6*106 m3/year. Due to the relief of hydraulic pressure, saline water is
