摘要 针对掘进巷道底板存在的泥化问题,依靠X射线衍射(XRD)、扫描电镜(SEM)等实验分析了泥岩的矿物成分、有机质作用,对泥岩泥化作用机理及影响因素进行了研究,得出了泥岩的黏土矿物成分主要是由伊/蒙混层、伊利石、蒙脱石、高岭石和绿泥石等组成,泥岩中的有机质加剧了泥化趋势,巷道积水、裂隙水、层间水、结构水等降低了泥岩的强度,泥岩的泥化是水、裂隙、动载荷、有机质等共同作用的结果,最后提出了泥岩巷道泥化治理的措施。 The paper is aimed at eliminating the problem of pedestal muddy arising in excavation tunnels, Site investigation and theoretical analysis and X-ray derivation(XRD), scanner electron microscope (SEM) experimentation analysis of mineral composition of shale, the effect of organism, and the study of shale's muddy mechanism and affecting factor are combined to point to the conclusion that clay mineral of shale is made of I/S, ileite, montmorillonite, Kaohng, turquoise and so on and organism aggravates shale's muddy tendency, accumulative water, crack water, stratum water, structural water detract intensity of shale, the result of which is water, crack, moving load, organism mutual effect. The paper gives some disposal measures for shale muddy mechanism.
