They are usually used in underground mining, if mining is done by drilling and blasting. They are also used in tunnelling, if hard rock prevents use of tunnelling 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.

#0183;#32;Since their first success in 1954, moles (mining machines) have been rapidly adopted worldwide. Close copies of the Oe moles were used for similar largediameter tunnels in clay shale at Gardiner Dam in Canada and at Mangla Dam in Pakistan during the mid1960s, and subsequent moles have succeeded at many other locations involving tunneling through soft rocks.
We have therefore used our expertise in mechanized tunnelling to develop innovative machine concepts for a variety of applications in mining. Whether for vertical access or production shafts, inclined vehicle access ramps, ventilation shafts or transport routes, Herrenknecht technology is designed for smallest and largest diameters and can reach depths of up to 2,000 meters.

Tunneling: Tunnels are an increasingly important element in today''s infrastructure. Not only are they used to provide an easy crossing through mountainous regions for road and railbound traffic. Increasingly they are also used in urbanized areas to augment overloaded roads, to provide quicker routes through crowded cities, and to reduce noise and pollution impacts on residents.

By the time World War II started in 1939, mining warfare was not of much use as the tunnelling was too slow to keep up with the movements of troops. There have been some more recent examples of tunnelling as a military tactic, most notably by the Viet Cong during the Vietnam War, but there has not been anything approaching the scale of the military mining used during WWI.

Tunnel boring machines (TBMs) and associated backup systems are used to highly automate the entire tunnelling process, reducing tunnelling costs. In certain predominantly urban applications, tunnel boring is viewed as a quick and costeffective alternative to laying surface rails and roads.
A tunnel boring machine (TBM), also known as a quot;molequot;, is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock may also be used for can be designed to bore through anything from hard rock to diameters can range from one metre ( ft) (done with microTBMs) to metres (58 ft) to date.
Hand Mining. The simplest form of soil excavation, Hand Mining is a method of constructing a tunnel in reasonably stable ground conditions. The tunnel must be large enough for personnel entry, and the tunnel face is manually excavated with hand held tools.
