摘要： 为了改善综放工作面巷道支护效果，提高巷道稳定性，以裕泰煤矿15104 综放工作面回风巷道地质条件为基
础，根据巷道围岩的力学性质确定了巷道支护参数，并在现场实践。由监测结果可知，巷道围岩顶底板移近量最大为
100 mm，两帮移近量最大为85 mm，围岩变形量较小，巷道稳定性较好。

Abstract: In order to improve the supporting effect and stability of roadway in fully mechanized top coal caving face, based on
the geological conditions of return air roadway in 15104 fully mechanized top coal caving face of Yutai Coal Mine, this paper
determined the supporting parameters of roadway according to the mechanical properties of surrounding rock of roadway, and put
them into practice on site. From the monitoring results, it can be seen that the maximum roof and floor displacement of roadway
surrounding rock is 100 mm, the maximum two sides displacement is 85 mm, the deformation of surrounding rock is small, and
the stability of roadway is good.

Key words: surrounding rock mechanics; roadway support; surrounding rock deformation
