Open Pit Mining an overview ScienceDirect Topics

Open pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow Figure 8 8 Open pit mine [16] Surface mining is usually used to develop coal seams and deposits of many other minerals but their feasibilities vary with the nature of the body ore

The influence of the scale of mining activity and mine site remediation

remediation of mining associated point sources has often been focused upon improving river water quality; however this study evaluates the contaminant legacy present within river sediments and attempts to assess the influence of the scale of mining activity and post mining remediation upon the magnitude of phe contamination found within …

Distinguishing between Deep Water Sediment Facies Turbidites MDPI

The distinction between turbidites contourites and hemipelagites in modern and ancient deep water systems has long been a matter of controversy This is partly because the processes themselves show a degree of overlap as part of a continuum so that the deposit characteristics also overlap In addition the three facies types commonly occur within interbedded sequences of continental margin

Natural Processes and Anthropogenic Activity in the Indus River MDPI
