Another recently developed tunnelling machine is the mole, a long machine with a circular cutting head that rotates against the face of the tunnel. Attached to the cutting head is a series of steel disc cutters that gouge out the rock on the face as the machine rotates and is pushed forwards by hydraulic power. Moles provide several advantages over drilling and blasting. The tunnel can be bored to the exact size desired, with smooth walls, thus eliminating the condition called overbreak, which results when explosives tear away too much rock. The use of moles also eliminates blasting accidents, noise, and earth shocks. Workers are less troubled by fumes and noxious gases and can clear away broken rock without stopping for blasting intervals. A mole can advance about 76 m (250 ft) a day, depending on the diameter of the tunnel and the type of rock being bored.
