摘要
破碎顶板是影响综放工作面安全生产的客观难题,一矿在81304综放工作面破碎顶板段进行加固煤岩体材料应用,对工作面顶板进行注胶维护,加固破碎围岩,保持围岩的完整性,有效地提高围岩的整体强度、改善支护体的支护特性,降低巷道变形量,使围岩承载能力得到显著提高,有效管控三角煤区段的顶板和煤壁。
The broken roof is an objective problem affecting the safety production of fully mechanized caving face.The first mine is used to reinforce coal and rock mass material in 81304 fully mechanized caving face. It can effectively improve the overall strength of surrounding rock, improve the supporting characteristics, reduce the deformation of roadway, improve the bearing capacity of surrounding rock, and effectively control the roof and coal wall of triangle coal section.
