A classification of the levels of convergence of geoinformation resources in economic systems is proposed, which puts information technology solutions, services, platforms, infrastructure and categories that the subjects of the economy solve in the process of forming value chains of tasks. The use of convergence of information, financial and material flows is considered, mechanisms of the received synergetic effect are established. A technique for numerical estimation of such an effect is proposed, as well as a mo...

The copper ore deposit in Poland is extracted by three underground mines which belong to KGHM Polish Copper JSC. Since the very beginning, copper ore mining has been accompanied by seismic activity and rock-burst hazard controlled by means of several prevention activities aiming at assessing and combating the danger. Seismology is the prime method to measure seismic activity i.e. the number and energy of rock mass shocks. The hazard monitoring also encompasses measurements of the convergence of mine workings, i.e....
