%X By introducing the basic principle of the microseismic monitoring technique and the components and structure of the ISS microseismic monitoring system used in Dongguashan Mine,the relative concentrating area of the geostatic activities is compartmentalized in the first mining area of Dongguashan ore deposit within different periods.The system and the principle of the seismology are adopted to study the intensity distribution of the stress and displacement to discover the temporal and spatial change rules of the geostatic activity produced by the mining and to evaluate the geostatic activity situation and the stability of the insulating pillar and main mining area.The study indicates that the change of the concentrating area of geostatic activity is dependent on the underground mining activities.Every concentrating area is corresponding to the position of each mining project.The geostatic activity changes in time and space with the change of mining project position accordingly.The geostatic activity within the mining area of stope is relatively stable.The distribution of geostatic activity in excavating area is separate and reduces quickly or even disappears with the completion of excavation.The rock mass within the first mining area of Dongguashan ore deposit is stable now.The practice proves that the microseismic monitoring technique is an effective method to study the rule of geostatic activity in deep mining.The result settles an important base for Dongguashan Mine to produce safely.
