摘要
本文通过矿压观测了解软岩巷道变形破坏规律，根据不同岩性巷道采用不同力学性质的支架，研制出平顶曲腿支架解决了以水平应力作用为主的巷道支护问题，获得良好的效益。
In this paper, the reqularity of deformation and failure of the softrock roadway is obtained by observing rock pressure, and according to the principle that the supports with different mechanical properties are adopted eorresponding to roadways in different rock strata the flat beam and curved leg support is developed to soloe the supporting problem of the roadways to which the stress is mainly horizontal resulting in better benefits.
