Underground Mining Methods Glossary Bolting
Truck and shovel excavation systems are very common and efficient methods in surface mining. They are very adaptable to change in peak geometry in the advent of variations to geology or to sudden failures. They involve a relatively low capital cost and additional equipment can be obtained at short notice. In addition, they have higher resale value.

Crushing and screening for sustainable excavation
Aggregate production. This is the most straightforward of the processes and has been used on countless tunnelling projects worldwide. Effectively this involves reduction of excavated rock to a size suited for further processing, then sizing to the required dimensions of 0-5mm; 5-10mm; 10-40mm, 40-100m and so forth.

Below the surface: Setting up an underground primary jaw
Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.

tunnels and underground excavations
Tunnels are generally grouped in four broad categories, depending on the material through which they pass: soft ground, consisting of soil and very weak rock; hard rock; soft rock, such as shale, chalk, and friable sandstone; and subaqueous. While these four broad types of ground condition require very different methods of excavation and ground support, nearly all tunneling operations
