The impact of coal exploitation on the geological layers of the earth is closely related to mining activities and this activity has been quite pronounced considering the topographical changes of the green space together with the vegetation that would directly affect the degradation of agricultural lands. The soil is the environmental medium with irreparable damages from the activity of coal exploitation for the location where the Sibovc mine is located, which is characterized by the physical disappearance of the pedological profile of the soil such as the ecosystem, etc. and that represents the most serious form of damage to her. The purpose and importance of this paper is the biological recultivation of the area degraded by coal exploitation, based on the height of the scale H and the angle α° of the slope of the clay layers with the safety factor allowed for determining the humus layer for the cover of the degraded area, physical and chemical analyzes were performed based on the samples that were taken in the open profiles in the field, it was planned to plant saplings (trees) that will have a positive effect on the prevention of soil erosion, the enrichment of the air with O2, the reduction of the amount of CO2 in the air, the prevention of the distribution of dust in the environment, the size of the passage and from the geotechnical point of view, the prevention of humus soil landslides. The planned recultivation of the plot will start from the level of quota 570, 580 and 590 m, covering an area of about 17 hectares.

Environmental degradation often occurs either from natural phenomena such as earthquakes, floods from Surface or underground water, but it often happens that the human factor itself can be the cause in cases where, by developing certain activities, it destroys the structure and texture of the environment’s landscape. As a concrete case of this study, the limestone source in the village of Pasomë is taken, where limestone is being exploited, the study aims to find solutions through which the sliding of the side slopes and the degradation of the environment will be minimized, since this directly affects the life and activity of the inhabitants of the village, over 70% of whom are engaged in agriculture and farming. The purpose of this paper is to find adequate solutions for the rehabilitation of the side slopes of the limestone source by creating the geometry of the side slopes with the safety factor allowed according to geotechnical standards to enable the re-cultivation of the source area where limestone was extracted because the vegetation plays an important role in creating a better environment for the inhabitants of the village and in general, as well as the preservation of flora and fauna.
