Aiming at the common problems,such as high stress,strong disturbance and difficult regulation in deep mining,the research on the dynamic regulation technology of mining ground pressure in deep large ore sections was carried out.By developing high-precision microseismic positioning technology based on forward numerical simulation and inversion positioning compensation,the intelligent distributed microseismic monitoring equipment suitable for deep well high temperature conditions and high-energy absorption support system,the correlation models between stress transfer and mining process parameters in the mining process of deep metal deposits and the quantitative early warning method of dynamic disaster safety were established,so as to realize the dynamic regulation of mining environmental ground pressure in deep large ore section.Research on mining environment monitoring and dynamic regulation technology of ground pressure in deep large ore section achieves a new mode of dynamic regulation of ground pressure in deep mining based on mining environment model-perception of multi-source measured data-analysis and back analysis discrimination-mining process adjustment-ground pressure measured feedback,which improves the intrinsic safety of the mine and provides technical guarantee for ground pressure control in deep large-scale mining.
