Influence of mining operations which took place in coal mining process on physical properties of sandstone have been investigated by means of comparison of apparent density, density of hard phase and opened porosity based on results of core assay of geological prospecting holes and mine workings. It was set that apparent density and coefficient of the opened porosity of sandstones from zone affected by mining operations substantially differ from the proper indexes in natural array. It is shown that such volume expension due to cracks formation promotes forming of sandstones permeability corresponding to the III class collectors.
