本文从巷道围岩控制论高度出发，以降低围岩应力、提高围岩岩石力学参数和选择合理的支护参数为途径，以大幅度降低围岩变形量为目标，以铁法矿务局小康煤矿为工程背景，探讨了综放工作面回采巷道中沿空巷道的支护机理，并进行了实践，有效地控制了综放工作面沿空巷道围岩的剧烈变形。
In this paper, from the perspective of the controllability of roadway surrounding rock, in order to reduce the surrounding rock stress, improve rock mechanical parameters of surrounding rock and select reasonable support parameters as a way to greatly reduce the deformation of surrounding rock as the goal, The coal mine is the engineering background, discusses the supporting mechanism of gob-side entry in the fully mechanized caving mining face, carries out practice and effectively controls the drastic deformation of gob-side entry in fully mechanized caving face.
