ABSTRACT

The objective of mine closure is to prevent or minimize long-term environmental damage, and to create a self-sustaining natural ecosystem or other land use based on an
agreed set of objectives. The Romanian mine closure legislation should be enforced in the coming years for taking best follow up actions and management of post mining closure. The mine closure is a process which should begins during the pre-feasibility
phase of a project and continues through operations to lease relinquishment. The closure of mining operations does not lead to the complete and permanent elimination of risks
and harmful effects are likely to affect the surface within the geographical limits of the
old mine workings. Therefore, during the period following the extraction, traditionally known as the „post-mining” period, several kinds of problems may develop, sometimes
just after the closure process but also, much later. These phenomena may generate
major consequences for people, ground, water, atmosphere and infrastructure. They are
also likely to have a major influence on regional development in mining areas.
Therefore the elaboration of evaluation methods able to identify and assess the residual
risks that may affect people and properties after closure is of great interest. Emphasizing
the basics and benchmarks specific for post-mining hazard assessment process the paper
develops a primary classification of applicable methods, with respect to main methods
selection parameters such as data availability, economic considerations and regulatory
considerations. The criteria for selecting the best adapted hazard assessment methods
for the specific conditions of Romanian collieries are also outlined in the paper.
