沿空留巷整体浇注护巷带主要参数及其适应性

Main Parameters of Pack Filling for Retained Gob Side Entry and Its Adaptability

通过现场实测和理论分析，对不同围岩条件下老顶断裂引起的整体浇注护巷带的支护强度和变形能力进行了深入研究，提出了使沿空留巷巷道保持稳定的整体浇注护巷带支护强度与变形的理论计算方法，进而对沿空留巷整体浇注护巷带的适应性进行了研究．

Through the statistical and theoretical analysis for the in situ examples of retained gob side entry, the roof cut load and deformation of its pack filling induced by main roof breakage are systematically studied for different surrounding rock of roadway. Furthermore, the theoretical methods of calculating reasonable supporting strength and deformation of retained gob side entry are put forward. Additionally, the applicable ability of pack filling is also discussed.
