Abstract

GEOTECHNICAL INVESTIGATION OF DRAGLINE DUMP OF JAYANT OPEN CAST MINES

Amit Golder* and Indrajit Roy

ABSTRACT

Surface mining operation often results in removal of huge quantities of waste material and subsequently dumping it outside quarry areas or back filling in the excavated areas as the case may be. In recent years the unprecedented increase in the rate of accumulation of waste dumps has been a great environmental concern because this leads to more frequent large/small dump failures. General increase in environmental awareness has given rise to concern about safe and economic design of waste dump both during mining and following mine closure. On the one hand, stable slopes are essential for safety of men and machine and on the other hand vast amount of land and money can be saved by optimizing slope geometry of dump. It is therefore, a technical and economic necessity that the most efficient compromise be achieved, in the light of these two conflicting requirement; by optimizing the slope that is steep enough to be economically acceptable and flat enough to be safe. The intension has been to produce design graphs and tables covering wide range of each controlling parameter for mine planners and operators to select optimum slope geometry of waste dumps.
