Used Underground Tunnelling machinery
Another name for a Underground Tunnelling Rig is a Drilling Jumbo. They are usually used in underground mining, if mining is done by drilling and blasting. They are also used in Underground Tunneling, if hard rock prevents use of Underground Tunneling machines.
A drilling jumbo consists of single or multiple rock drill carriages, Modern drilling jumbos are relatively large, there are however smaller ones for use in cramped conditions.
We have an extensive range of underground drill rigs for mining development, Underground Tunneling and production.

Selecting a drill rig.
Considerations for a buyer are the mechanical and hydraulic features that will maximize production. Tramming speed is one such feature. That is, how easily can a particular drill rig “tram,” or move itself, from a drilled rock face to the next rock face to be worked. Typically, these machines can’t move quickly—normally less than 10 mph. Yet nimbleness and speed are relative. Every non-drilling minute reduces a shift’s total production, so one or two mph makes a difference.
A buyer should also consider the speed with which a drill rig can position its boom or booms for drilling, because the speed of this set-up process also helps determine a shift’s output. After aligning itself for drilling, a drilling rig’s rock penetration and hole-flushing rates are next thing to consider. From the time you position a drill and start drilling, a hole will be drilled in anywhere from 50 seconds to two and a half minutes depending upon the hardness of the rock.
Another choice is between single-boom drill rigs and two-boom rigs. Because of other factors, production of a two-boom rig vs. a single-boom drill is not 2-to-1. Normally, the two-boom rig will drill 1.5 to 1.7 times what a single-boom rig can drill. It depends on the operator and the hardness of the rock.
Tunnelling and Underground Space, Trenchless Technology.
Tunnels and underground excavations – Tunnelling techniques: Tunnels and underground excavations are usually horizontal underground passageway produced by excavation. A vertical opening is usually called a shaft. Tunnels have many uses: for mining ores, for transportation including road vehicles, trains, subways, and canals and for conducting water and sewage. Underground chambers, often associated with a complex of connecting tunnels and shafts, increasingly are being used for such things as underground hydroelectric-power plants, ore-processing plants, pumping stations, vehicle parking, storage of oil and water, water-treatment plants, warehouses, and light manufacturing, also command centres and other special military needs. Tunnelling techniques using Trenchless Technology, 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.
