变特性是软岩固有的属性，在长期荷载作用下的软岩巷道支护设计必须考虑岩石的流变特性.针对“三软”煤层巷道围岩大变形、难支护的具体情况，以显德汪矿主输送大巷为研究对象，进行了三轴压缩流变试验，获取了泥岩的流变参数，进而为下一步的软岩巷道支护设计提供了科学的依据.

Rhelogy is the intrinsic characteristic of the weak rock, and the rhelo gical characteristics have to be thought in the design of weak rock. Thinking of the large deformation and difficult support of weak tunnel, with the main tunnel of Xiandewang Coal Mine as an example, the rhelogical test is done, and the rhelogical parameters of mudstone have been obtained. Moreover, the direct scien tific basis was provided for the weak tunnel support.
