Influence of mining operations on the change of pressure in undermining coal rock massive have been investigated by application of two methods: first – linear pressure decline from maximal values at the beginning of the affected zone of mine workings to atmospheric, at excavation and second – based on definition of water level in an access borehole. It was set that permeability, in undermining massive increases and can arrive at 300 – 400 10-15 m2.
