Introduction. The article considers the problems of the present-day algorithm of acoustic emission events location in Prognoz-ADS geomechanical monitoring system. The ways of solving the flaws in the applied algorithm have been proposed with the account of the specified requirements. Research aim is to propose certain solutions aimed at achieving higher accuracy of seismoacoustic events coordinates calculation; to solve the flat antenna problem and get the opportunity of assessing the

... of separate observing network elements; develop the structure of a new location algorithm and calculate its preliminary complexity. Methodology. It is proposed to correct the problems of the existing algorithm by constructing the velocity map of the controlled object and assessing the efficiency of seismoacoustic receivers and data on the observing network sensitivity in various sections of the rock mass. Results. The article provides logical structure of the developed algorithm with complexity O(n). It is proposed to solve the flat antenna problem by using data on seismic receivers complex sensitivity. Certain media of collecting information on the observing network state and signal propagation velocities at the controlled object have been introduced. Summary. The designed algorithm provides for multiple parameters variation, many of them are not taken into account in the existing location method of Prognoz-ADS system. The indicated characteristics selection and the efficient use of the calculating tool's hardware resources will make it possible to obtain a more accurate and universal location algorithm.
