流动围压在井巷掘进工程中的影响分析与对策

Effect and Countermeasure of Ambulatory Confining Pressure in the Project of Underworkings Development

顺利通过在断层破碎带、岩溶裂隙及溶隙中,因溶蚀、变质及充填等复杂地质作用而形成的松散结构岩体带,能够提高巷道围岩稳定性,创造良好的安全生产条件。

Successfully overpass free - open - textured massifs, which were formed by many geological actions such as solution, metamorphosing and fill, in shattered fault zone, karst caranny, space of dissolution. So the stabilization of well rock in underworkings was enhanced. In this way, good safety productive condition could be produced.
