Mining of rock minerals, constitutes a strong stimulus for economic development and at the same time, can significantly and negatively affect the state of natural environment, roads and well-being of local communities. This paper presents methodology for studies of spatial impact of rock minerals mining in the Lower Silesia region (SW Poland). In the region majority of magmatic, metamorphic and other rock minerals occur in Poland and their intensive mining is an important sector of regional economy. The concept of mining density (mineral production per unit area) has been introduced and the changes of rock minerals mining in the period of the last 8 years (2006-2013) have been analysed and presented graphically with GIS-based methodology. Mining density increased from 2006 to 2011 and decreased from 2011 to 2013. Change in the spatial pattern of mining density between 2006 and 2013, despite comparable volume of rock minerals production, has been identified. In addition proximity of mines to human settlements, nature protection areas and railways (potential transport routes) has been analysed. Comprehensive and coherent information on rock minerals mining for the area of Lower Silesia provided in this study has been used in developing and implementing regional spatial development policy and attaining the balance between the economic needs, nature protection requirements and the well-being of its citizens.
