摘要
层滑带在华北断陷盆地中具有普遍性，是影响地下矿山工程围岩稳定的重要因素之一。本文以鲁西矿区为例，阐述了断陷盆地层滑带的发育特征及其形成机制，进行了开挖、运营条件下层滑带再变形分析。
Seam sliding zones are commonly found in faulted depression basins in Nor th China and become the important factors influencing the stability of their s urrounding rockmass in underground miningworkings. Taking mining areas in weste rn Shandong as examples, this paper discusses development characteristics of sea m sliding zone and its formation mechanism, analyses its repeated deformation u nder the conditions of excavation and operation, and points out some problems to which should be paid attention during roadway designing and maintaining near th e seam sliding zone.
