Study on fault slip dynamic response and rock burst potential under the influence of different horizontal stresses

The seismic source release by fault slip under the influence of mining is an important factor to induce rock burst. In this study, normal and reverse with different horizontal stress are constructed numerical simulation law stope dynamic response characteristics when panel through faults compared analyzed. Studies show that fault, level higher, so shear strength greater. When coal pillar small disturbance severe, displacement increases significantly, drops suddenly, Under load, vibration velocity mass near space, reduction value advanced abutment pressure affected range larger, burst more likely occur. on-site statistical cases consistent results, verifying reliability methods conclusions.
