Research and application of high performance steel fiber concrete wall in deep shaft passing through outburst coal seam group
Aiming at the support problems when the coal mine deep vertical shaft passes over the outburst coal seam group, the use of steel fiber concrete shaft lining structure is proposed. Firstly, the benchmark mix ratio of high-performance concrete for shaft lining is obtained through orthogonal design con...
