Hydrogeochemical modelling of corrosive environment contributing
Anchor bolts are commonly used throughout underground mining and tunnelling operations to improve roof stability. However, premature failures of anchor bolts are significant safety risks in underground excavations around the world due to susceptible bolt materials, a moist and corrosive environment and tensile stress.

New rockbolting methods for reinforcing tunnels against deformation
The model tunnel was a 1/30 scale model of a single-track, non-electrified tunnel. The model tunnel lining was 13 mm in thickness to simulate the actual tunnel lining thickness of 40 cm in prototype. The length of the rock bolts in model was 133 mm replicating the actual rock bolt length of 4 m. Table 1.Wang Qi et al. [26, 27] used grouting anchor cable active support instead of passive often found in mining [1, 2] and tunneling cutting with high-strength bolt grouting with the deep mining.Research on an automatic roadway formation method in deep mining
