THE ECOLOGICAL RECONSTRUCTION THROUGH AFFORESTATION WORKS ON THE RUNCURELUL DUMP HAVING THE AREA OF 27 HA

DINUCĂ NICOLAE CĂTĂLIN, BERCEA IULIAN

Abstract


In recent decades, surface mining operations, especially in the mining basin of Oltenia, have developed a lot and as a result there have been large areas with degraded land and tailings dumps whose ecological reconstruction has been and is a topical issue.

The Runcurelu Dump is located within the Jilț Quarry, the territory of commune Mătăsari, more precisely in the Runcurelu meadow and is free of technological tasks. The spontaneous vegetation settled quite well, especially on the first plateau. Because the piled material was deposited in a completely random way, the surface of the perimeter is largely uneven, especially on the two slopes that border the plateaus. On the slope the slope is large and complex, ranging between 25-35% and over.

From a geological point of view, the studied perimeter is very complex, belonging to both the Pliocene (Levantine) and the beginning of the Quaternary and Dacian (sands).

Lithologically, it is represented by various inhomogeneously mixed geological materials. Following the coal mining process, respectively the dump process, the geological deposits of a great diversity were brought up to date and mixed very heterogeneously.

The diversity of dumped materials is observed both chemically and physically. In this dump are alternately deposited all sorts of materials, from clays, marls, to sands with smaller or larger coal fragments.
