Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Tunnel boring machine

Tunnel boring machine

A tunnel boring machine (TBM), also known as a "mole", 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 bore through anything from hard rock to sand.Tunnel diameters can range from one metre (3.3 ft) (done with micro TBMs) to 17.6 metres (58 ft) to date.
