The article discusses optimization of microseismic monitoring in hard mineral mining. A procedure has been developed to estimate accuracy of positioning of seismic event hypocenters. The advantage of combination observation system with distributed underground receiving antennas and additional sensors installed at a distance from a productive seam plane is illustrated. The obtained results are important for optimizing observation systems and improving efficiency of microseismic monitoring in hard mineral mining.
