赵庄矿13092复用巷道注浆加固技术研究

Research on Grouting Reinforcement Technology for the 13092 Multiplex Roadway in Zhaozhuang Mine

针对赵庄矿复用巷道变形量大、影响正常使用的问题,通过两次采动变形规律实测研究得到了复用巷道受采动影响的变形规律,对煤柱侧和工作面侧进行了注浆设计。现场应用表明,注浆区域变形量远小于未注浆区域,注浆加固后复用巷道变形量满足了二次回采期间使用要求。

Aiming at the problem of large deformation amount in the multiplex roadway of Zhaozhuang Mine,which affects its normal use,the deformation law of the multiplex roadway affected by mining is obtained through two actual tests and research on the mining deformation law.Grouting design is carried out on the coal pillar side and the working face side.The on-site application shows that the deformation amount in the grouting area is much smaller than that in the non grouting area,and the deformation amount of the multiplex roadway after grouting reinforcement meets the requirements for use during secondary mining period.
