Analysis of potential instability mode of shallow buried longitudinal cross roadway
Aiming at the problem of continuous large area caving in a mine transportation roadway,the distribution of caving under different exposure time and after filling was calculated by FLAC and PFC3 D coupling program through numerical analysis method.The results show that the caving will continue to occur.With the increase of exposure time,the caving in the contact road and 5#inclined shaft continues to develop,among which the first month's caving is the most serious.The caving concentration area is dominated by the contact road and its intersection,which provides a certain reference for underground mining under the same conditions.
