“三软”煤层巷道围岩变形破坏机理分析

Analysis on deformation failure mechanism of surrounding rocks in 'three soft seam roadway

从沉积岩石学和工程地质力学的观点出发 ,以显德汪矿的软岩巷道为研究对象 ,进行了大量岩石物理力学性质试验 ,深入研究了岩石物化、水理性质 ,探讨了地应力对软岩巷道的控制作用 ,得出了软岩巷道变形破坏力学机制的新认识。

The paper had a great performance tests of rock physical mechanics with a research aiming at the soft rock roadway in Xiandewang Mine from a view of sedimentary rock mechanics and engineering geological mechanics. The paper had a deep research on the rock physical chemistry and water physical features. The paper discussed the earth stress to the control function of the soft rock roadway. The paper has a new understanding of deformation failure mechanics mechanism of the soft rock roadway.
