Impact of Depressurizing Boreholes on Energy Dissipation in Deep Roadway
Geofluids, 2022 Depressurizing borehole drilling is an effective approach to control the large deformation of deep roadway. It can transfer the high stress in the proximity of the roadway into the deep stable rock masses. However, it should be noted that the borehole drilling will inevitably cause the secondary damage to roadway.

KSCE Journal of Civil Engineering, 2018 We proposed a new classification method for stress-bearing structures in very-deep roadways. We conducted tests for roadwayengineering mechanical properties, including rock mechanical tests and ground stress measurement of two caverns in very-deep wells. We suggested a classification method for stress-bearing structures based on shear stress.
