【摘要】 通过对千米深井按五水平、分岩性及是否受采动影响底板岩巷围岩松动圈的实测分析，着重探讨了围岩松动圈与采深及受采动影响下的变化规律等，并对深水平巷道围岩松动圈进行预分类，据此进行工业性试验，取得了良好的效果更多还原

【Abstract】 The change in the thickness of broken zone in surrounding rock of roadways with mining depth is discussed on the basis of its observation data for deep roadways located at different levels and in different rocks. As a result, a scheme of the pre classification for deep roadways in the mine is put forward, its satisfying results having been acquired in an industrial trial.更多还原
