Since their first success in 1954, moles have been rapidly adopted worldwide. Close copies of the Oahe moles were used for similar large diameter tunnels in clay shale at Gardiner Dam in Canada and at Mangla Dam in Pakistan during the mid 1960s, and subsequent moles have succeeded at many other locations involving tunneling through soft rocks.
Komatsus tunnel equipment provide an efficient, reliable, cost effective and lower risk method of removing material from tunneling excavation sites. We are a worldwide leader in the manufacture and sale of conveyors designed and built to withstand the harsh conditions of tunnel construction.
Drilling machinery, equipment used to drill holes in the ground for such activities as prospecting, well sinking , and scientific explorations. Drilling holes in rock to receive blasting charges is an operation in tunneling, mining, and other excavating. oil drilling rig.
CMM Equipments designs and manufactures custom vehicles for all activities in underground mining, quarrying, construction or tunnels. The main vehicles are jumbos for drilling amp; purging, transportation of personnel vehicles, core drills, scalers, etc.
A tunnel boring machine , 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 strata. They may also be used for microtunneling. They can be designed to bore through anything from hard rock to sand. Tunnel diameters can range from one metre to 17.6 metres to date.
Used Underground Tunnelling machinery Another name for a Underground Tunnelling Rigs and machinery 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.
