Extractive industry has had and has negative effects on environmental factors. Limitation of industrial activities carried out in Jiu Valley, materialized by closure of mining units, brings to actuality the rehabilitation of areas occupied by constructions and surface utilities related to the technological process of underground coal extraction. First stage of surface rehabilitation and greening is the demolition of surface buildings by means of technical implosion / blasting or classic techniques. This stage generates a series of physicochemical pollutants that can have a significant impact on environmental factors. The main objective of the current paper is to identify pollutants and the negative effects they may have on human health as well as to reduce the environmental impact of materials from demolition operations. The paper has the advantage of quantifying waste resulting from demolitions in order to reduce impact on the environment by revalorizing the obtained materials (metal, concrete, wood, brick etc.) thus reducing the quantities of industrial waste to be stored. Thus, it is possible to plan the greening of areas affected by mining activities in the shortest possible time, correlated with the program of territorial systematization, in order to capitalize on new economic opportunities for use of these lands.
