高档工作面断层破碎带顶板注浆加固技术

Grouting reinforcement technique in fault broken roof in working face with individual props

提出采用顶板注浆加固技术预防断层破碎带顶板的垮落,分析了高水注浆加固材料的力学性能、注浆加固工艺及加固参数.现场实践表明,采用此项技术基本解决了断层破碎带顶板的垮落问题,取得了较好的技术经济效果.

Roof grouting reinforcement technique was used to prevent fault broken roof from falling. Mechanics characteristics of high water content grouting reinforcement material, reinforcement technology and parameters were also analyzed. Practical applications indicate that the falling of fault broken roof can be basically solved and good technical and economical benefits can also be obtained.
