摘要: 以顾北矿南翼(11-2)煤层回风巷过F104断层异常带巷道为工程背景,介绍了断层区域岩石裂隙发育,局部富水性较强,岩层软化膨胀变形、泥化程度高等支护特点,在掘前超前加固及掘后有效支护、充分利用和发挥围岩的自承载能力的基础上,用理论分析、数值模拟和现场试验相结合的综合研究方法,系统研究了顾北矿F104断层异常地质构造带巷道安全掘进与加固技术,结果说明了围岩经过注浆加固后裂隙得到充填,巷道围岩没有出现新的裂隙及离层现象,顺利通过断层构造带,取得工业性试验成功。

Abstract: Abstract: South wing of Gu Bei coal mine (11-2) through the seam to return airway abnormalities F104 fault Zone Roadway engineering background, introduce the development of rock fractures in the fault zone, the local water rich, the deformation of rock deformation and the characteristics of the high degree of mud, on the foundation of the pre reinforcement and excavation of the effective support, the full use of the surrounding rock and the capacity of the surrounding rock, using comprehensive research method of theoretical analysis, numerical simulation and field test, system research Tunnel safe driving and reinforcement technology of Gu Bei coal mine in the F104 abnormal tectonic fault zone, results show that no cracks and separation phenomenon of new the surrounding rock after grouting fractured surrounding rock filling,passed Fault Zone smoothly, made a successful industrial test.
