STUDY ON RELATIONSHIP BETWEEN SUPPORT WITH BACKFILLING AND SURROUNDING ROCKS OF ROADWAY IN SOFT STRATA
软岩巷道支架壁后充填与围岩关系的研究

High resistance and yieldability of the support are the key factors to guarantee the stability of the roadway in soft strata. Poor loading condition will severely limit the supporting capacity of the supports in soft strata. Support backfilling, however can enable the supports to be loaded in early stage and uniformly, resulting in therefore great rise of the working resistance of the supports and hence effective control for the large deformation of the roadways surrounding rocks.
