glossary of mining terms coal educationa. 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 roadwayand (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. construction and mining equipment,formwork equipment all cep10 is a light prop that is easy to handle and has a covered thread and a minimum capacity of 10 kn in accordance with the din/uni en 1065 standards. this prop is equipped with a 10 cm antihandcrushing device that can be inserted into hydraulic propulsion boat design nethydraulic drive units are in production and used quite a bit over seas, yet to catch on in the states. the engine can be run at the best rpm for the conditions, like an idling engine in a smooth sea with the prop spinning fast or in heavy going, slowing down the prop and spinning up the engine.
