摘　　要：本文对1606综采工作面过X3陷落柱时煤体、顶板岩层破碎,提出以注浆加固、布置撞锲的顶板管理措施,并详细对布置技术方案进行阐述。现场应用时,将工作面回采速度由3.2m/d提升至4.5m/d,避免顶板来压。通过注浆、撞锲支护后工作面煤壁、顶板均保持稳定,工作面耗时10d通过陷落柱,取得了显著应用成果。In this paper,when 1606 fully mechanized coal mining face passes through X3collapse pillar,the coal and roof strata are broken,the roof management measures of grouting reinforcement and arrangement of bumping wedge are put forward,the layout technical scheme is described in detail.In field application,the mining speed of working face is increased from 3.2m/d to 4.5m/d,avoid roof pressure.After grouting and wedge support,the coal wall and roof of the working face remain stable,the working face took10 days to pass through the collapse column,and achieved remarkable application results.
