Application of seismic wave CT inversion technology in stress distribution of No.1301 working face
There are multiple faults in the No.1301 working face,with three sides being mined out and having a moderate risk of im-pact.The stress distribution in the working face is constantly changing due to mining disturbance,fault,goaf and other factors,which has a greater impact on production and rock burst prevention.In this paper,the stress distribution in the mining process of the working face was analyzed by CT inversion technology,and the high stress area was divided more scientifically and intuitively,providing a reliable scientific basis for the prevention and control of rock burst and facilitating the effective implementation of the prevention and control of rock burst in the next step.
