Rock mass equilibrium is disturbed when rocks undergo excavation through mechanical or blasting techniques. When the disturbance is rapid, it leads to unstable zones in the structure even after completion of structure in long term, and hence it becomes essential to monitor such underground excavated structure behavior continuously using microseismic monitoring. Microseismic Monitoring (MSM) is an effective technique to locate zones of micro-cracking in the rock mass and further for the demarcation of potentially unstable zones in underground excavation. This paper gives a brief account of the Microseismic Monitoring System that has been applied in the underground powerhouse of Tala Hydropower Plant (THP). Stability of the underground powerhouse was analyzed using various microseismic source parameters. Based on one-year of continuous monitoring, potential unstable zones were identified at the powerhouse of THP. Microseismic Monitoring System thus provides information ahead and helps audit the safety measures taken at any site. Therefore, this technique is an effective way to evaluate rock mass behavior before occurrence of any disaster and helps to diminish the potential damages.
