ASSESSMENT AND MAPPING OF GEORISK IN MINING AREAS ABOVE ABANDONED CHROME MINES IN ALBANIA

Gafur Muka

Abstract :

 The major influence of underground abandoned exploitations in chrome mining areas in Albania are categorized as sinkholes, block caving and sometimes progressive hanging walls. These forms mainly relate to the sublevel open stoping mining method used, leading to the self–collapse of surrounding rocks located in the roof of the mineral body. Depending on the thickness of exploitable ore bodies, the thickness of the bedrock, the thickness of the diluvions and the size of underground cavities, there is a substantial impact on the ground surface or an extended zone of movement and collapse within the rock mass. Their appearance on the ground surface endangers the lives of people and animals, and may also damage the environment, or have an impact on the various facilities that occupy the surface of the mining region. As a result of this phenomenon, studies have been conducted in order to evaluate the potential impact and locations of upcoming sinkholes or subsidence in order to take the appropriate measures as to remove the objects from these areas, as well as the prohibition of the movement of people in the areas declared dangerous. In order to increase the security level of human activity on the ground surface and to realize a more effective use of land in the affected areas, studies have been conducted on the assessment of susceptibility of abandoned mining exploitations, classifying it into 5 classes. In this study, based on the intensity of susceptibility and the rate of vulnerability, the geo–risk is estimated and the mapping is performed using GIS technology.
