摘要
K8403综放工作面回风巷附近穿过陷落柱,为保证K8403工作面安全高效生产及最大限度安全回收煤炭资源,采用"注浆加固该陷落柱,加固巷道顶板"的措施使得工作面强过陷落柱。本文分析了注浆加固陷落柱的施工方案、工艺以及注浆量的确定,取得了显著的经济技术效益。
Subsided column crossed nearby ventilation roadway in K8403 fully mechanized caving face, in order to ensure the safety and high efficiency production of K8403 face and safely recover coal resources in maximum,measures of ＂grouting strengthen subsided column and strengthen roadway roof＂ had been taken to ensure subsided column cross face.The paper analyzed the construction scheme and technology of grouting reinforcing subsided column and determined grouting volume,which obtained remarkable economic and technological benefits.
