摘要 支架的高阻和可缩是确保软岩巷道稳定性的关键。受力条件恶化严重抑制着软岩巷道支架支撑能力的发挥。实施支架壁后充填使支架及早承载和均匀受力,可大幅度提高支架的工作阻力,有效地控制巷道围岩的强烈变形。 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.
