The waste rocks deposited in the dump that served the Jiet
shaft is unsuitable for the installation of vegetation, so that, at present,
the deposit makes a discordant note with the surrounding landscape, producing
chromatic and aesthetic disturbances. Coal mining activity in Jiu Valley is
approaching, faster than expected a few years ago, to its end and one of the
main directions for transforming the area (while ensuring its sustainability)
is the development of tourism. Under these conditions, a problem that has
remained partially unresolved is related to the integration of the former
mining perimeters, especially the waste dumps, into the surrounding landscape.
Such an approach must always start from a thorough check of the technical
condition of these artificial earth constructions. For this reason the
stability of the dumps in the Jiu Valley is considered to be an important
issue, considering that possible failures endanger both the natural and the
anthropic environment. In the case of the Jiet waste dump considered as a case
study, because several years have passed since the last sterile rocks were
deposited and since stability studies were performed, a new such study was
considered necessary (given that the deposited rocks underwent certain changes:
compaction, mechanical disintegration, chemical alteration, etc.). This paper
presents the results of the stability analyses carried out during 2022 and a
series of conclusions regarding the limits within which the geometric elements
must be framed so as to ensure a good stability reserve and thus allow the
ecological restoration works to begin.
