A self-drilling anchor (SDA) is a ground support system used in tunnelling, particularly in weak, loose, or fractured ground conditions where traditional bolting methods are challenging. It consists of a hollow steel bar with a sacrificial drill bit at the tip, which improves ground reinforcement while reducing installation time. SDAs are beneficial in unstable ground where borehole collapse is a risk. Rapid installation and effective application in difficult geologies are some of the advantages

The New Austrian Tunnelling Method (NATM) is a versatile and innovative approach adaptable to a wide range of geological conditions. It can be effectively applied in soft ground, soft rock, or hard rock environments. The method involves excavating tunnels in small sections and immediately supporting them with shotcrete, steel ribs, and wire mesh to strengthen the structure. At MEIL Group, we adopt NATM to deliver vital tunnel projects across the country, ensuring world-class infrastructure is bu

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

Various underground mining methods are employed depending on geological conditions. One prominent technique is longwall mining, particularly utilised in coal and other flat-lying deposits. In longwall mining, a continuous mining machine known as the shearer traverses back and forth along the face of a coal seam, cutting slices of ore. As the shearer advances, hydraulic supports, called shields, are installed to hold up the roof. Conveyor belts transport the extracted ore to the surface for proce
