Multi-Attribute Scenario Analysis of Protection of Drmno Open Pit Mine against Groundwater

Abstract

Drmno open pit mine with the annual yield of 9 million tons of coal is one of the main providers of the primary energy source in company Elektroprivreda Srbije. Due to the immediate vicinity of two rivers, the Mlava and the Danube, water abundance in the working environment is high and the problem of protecting the open pit from infiltration of underground waters is relevant to the execution of exploitation works. This paper is focused on the multi-attribute check of the preference of one of the two projected variants of the modification of the system for protecting Drmno open pit mine against the infiltration of groundwater. The outcome of the analysis confirms the signification and justification of applying a multiattribute or multi-criteria analysis for examining such problems.
