摘要
运煤巷道受富水泥灰岩破碎带的影响,易发生失稳变形,本文以某运煤巷道为工程背景,结合大量隧道注浆加固工程经验,制定出针对富水泥灰岩破碎带巷道的施工注浆方案,并以实际工程参数为依据,结合FLAC3D软件进行数值模拟,对巷道注浆加固效果进行验证,为类似工程问题的设计与施工提供一定的参考依据.
Abstract
Due to the influence of cement-rich limestone fracture zone,coal roadway is prone to unstable deformation.In this paper,based on the engineering background of a coal roadway,combined with a large number of tunnel grouting reinforcement engineering experi-ence,the construction grouting plan for the cement-rich limestone fractured zone roadway is formulated,and based on the actual engineering parameters,combined with FLAC3D software numerical simulation,the effect of roadway grouting reinforcement is verified,which provides some reference for the design and construction of related engineering problems.
