ABSTRACT

Legal requirements are nowadays requiring ever increasing environmental protection
levels, as a direct effect of the higher awareness degree of the impact induced by all
types of mining activities, including those related to mine waste disposal. As to the
structural stability of these mining waste deposits can be observed on slopes,
manifesting a progressive trend. Therefore, the risks induced by extreme atmospheric
phenomena or by their combination can have significant consequences, triggering
technological accidents. Detailed site investigation by experienced geologists and
geotechnical engineers is needed to determine possible potential for failure, with in situ
and laboratory testing to determine the properties of the foundation materials. Within
this context, in the first section of the paper, a systematic inventory is carried out
concerning the effects induced on the environment by tailing dams, being identified the
potential risks and the basic techniques which can be put in practice in order to prevent
the occurrence of undesired events with catastrophic consequences. On this basis, in the
second part of the paper there are emphasized the safety measures which should be
implemented both in operational stage, and after activities cessation, to provide an
adequate safety level of tailing dams.
