ABSTRACT: During
the fully mechanized caving face re-recovery process, due to the influence of
mining and the redistribution of surrounding rock stress, a higher advanced support pressure and lateral support
pressure will be formed around the working surface. The superimposed
advanced and lateral support pressure will have a greater impact on the
advanced support of the working surface roadway. In order to improve the stability of the surrounding
rock, the three Hebi mines were used as the subject of the study. At the same
time, Universal Distinct Element Code software was used to study the pressure distribution pattern of over-support at the working
face. Finally, the results of the study are used as theoretical support
and reference for the support scheme.
