Environmental impact assessment of open pit mining in

26/08/2008· Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by stone from the mining process in general and open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them.

An exploratory analysis and geostatistical modelling of the grades assayed on a set of drill hole samples is performed, which allows constructing a grade model on a dense grid by means of a conditional simulation. The grades are then averaged to greater selective mining unit supports in order to proceed with the study and methodology. First, the metal-tonnage

Open pit mining equipment Maccaferri Africa

An opencast or open-pit mine is used to extract valuable deposits close to the earth’s surface. Here the fragmentation, loading, materials handling and production control require heavy equipment. To maximise extraction volume and minimise the space for infrastructure, slopes within these mines can be steep. Material can detach from these slopes affecting mine safety and operations. Our
