Control technology and application of variable-diameter zoned pressure relief for surrounding rock in deep soft rock and large deformation roadway
Addressing significant deformation in the surrounding rock of deep soft rock road-ways subjected to repetitive repairs, this study focuses on the 21st transportation downhill of Quandian coal mine as the engineering context. We propose the variable-diameter partition roadway pressure relief technolo...
