摘要
软岩、极软岩巷道具有高地压、难支护和持续变形破坏工程特征,实践表明,现有支护难以耦合控制.文章通过对软岩工程特征、变形破坏机理分析研究,提出了软岩控制和复合型软岩向单一型转化控制的技术方法和实用支护对策.经工业性试验、应力监测表明,控制了围岩的强烈变形、保证了巷道的稳定,具有显著的技术经济效益.
The soft rock and extreme soft rock laneway have the characters of not enduring the high earth pressure,being difficult to support and continuous deformation destroying.The practice indicates that the existing supporting method is hard to control it by coupling. According to the analysis on the soft rock engineering character and the mechanism of deformation destroying, the technology and applied supporting strategy of soft rock control and the transformation from compound soft rock to single rock are advanced. The industry test and stress detecting show that the technology could prevent the wall rock from severe deformating and ensure the stabilization of the roadway. It has obvious technological and economic benefit.
