A. 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 ...
Mini Blast Furnace and Iron making. Mini blast furnaces (MBF) are generally viewed as miniature versions of the conventional large blast furnaces (BF).
On April 12, 2018, a 60-year old customer truck driver was killed when he fell from, and was run over by, his truck while scanning into the operator's check-in system.
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.
