In order to improve the processing and interpretation accuracy of microseismic monitoring of mine water damage, the relevant elements were analyzed, the TRIZ theory function model was constructed, the causal chain analysis was carried out，and the conflict area was found out. Using the principle of technical conflict resolution, the monitoring array was optimized and the spatial layered velocity model was established. Inspired by biological effects, active disturbance detection method was studied. Using the principle of physical conflict resolution, the space-time separation inversion analysis method was studied. Based on the evolutionary theory, a new mode of pre-clustered microseismic monitoring system and specialized technical service based on the Internet of things was formed, which effectively improved the accuracy of microseismic data processing and interpretation of mine water damage. Through the practical application in the mine site, the accuracy of microseismic event processing and interpretation met the requirements, which achieved good results.
