This video demonstrates the process of rock bolting and wire mesh installation in an underground mining project. These ground support techniques are essential for ensuring stability and safety in excavated tunnels and stopes. However, it is important to note that while this video shows the installation of wire mesh before the first layer of shotcrete, this is not considered best practice. The first layer of shotcrete should always be applied before installing wire mesh to ensure that personnel d

Caisson sinking and underpinning shaft construction techniques are illustrated in this video briefly. These methods are generally used in soft ground condition. The caisson sinking can also be divided into dry and wet method. You can learn all these techniques in our Online Tunnel Engineering course in details. Our course also cover many other shaft and tunnelling construction methods. Click the link below to find out more and complete your registration https://tunnel.engineering/register/tunnel
