摘 要:软岩巷道维护状况及围岩变形量与支护阻力的关系极大,实验与实践表明,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。he maintenance status and surroundingrock deformation of soft rock roadway haveimportant relation with supporting resistance.The experiments indicated that the highresistance and yieldability of support are the keyfor ensuring the stability of soft rock roadway,that the worse of applied force condition hadlyrestrains elaboration of supportihg ability ofsupport in soft rork roadway,that carrying outsupport wall back fill makes support be loadedearly and uniform1y, so that the workingresistance of support may be largely increasedand the deformation of roadway surroundingrock may be efficiently controlled.
