Study on Roof Deformation Mechanism and Dynamic Staged Control of Heading Area in Rapid Tunneling

Aiming at the problem that there are many factors influencing the stability of heading roof, and the unreasonable value of parameters leads to the low efficiency of heading, the mechanical model of heading roof is established, and the law of bending and sinking of roof is analyzed, based on the crit...
